Abstract
Fuchs Uveitis Syndrome (FUS), also known as Fuchs Heterochromic Iridocyclitis, is a chronic form of uveitis characterized by mild inflammation primarily affecting one eye. This study aimed to investigate the clinical and epidemiological features of FUS in an Iranian population. A retrospective analysis was conducted on 466 patients diagnosed with FUS at an ophthalmology center affiliated with Isfahan University of Medical Sciences between 2003 and 2021. The Kimura et al. criteria were used for FUS diagnosis. Demographic data, clinical characteristics, misdiagnosed cases, concurrent diseases, and associated ocular findings were analyzed. The study included 507 eyes of 466 FUS patients, with a mean age of 34.01 ± 11.25 years. Iris atrophy, keratic precipitates, and vitritis were common clinical findings. Heterochromia was an infrequent feature. Initial misdiagnosis occurred in 13 patients, with pars planitis being the most common incorrect diagnosis. Toxoplasmosis and multiple sclerosis were common concurrent diseases. Pediatric FUS cases were noted, possibly attributed to early-onset manifestations. Differences in clinical characteristics were observed when compared to other populations. This study provides insights into the clinical and epidemiological aspects of FUS in an Iranian population. Variations in clinical features, misdiagnosis patterns, and concurrent diseases were noted. Attention to specific clinical parameters can aid in accurate FUS diagnosis. Understanding these differences contributes to a better understanding of FUS presentation and its relationship with other diseases.

Abstract
BACKGROUND To investigate the genetics of early-onset progressive cerebellar ataxia in Iran, we conducted a study at the Children's Medical Center (CMC), the primary referral center for pediatric disorders in the country, over a three-year period from 2019 to 2022. In this report, we provide the initial findings from the national registry. METHODS We selected all early-onset patients with an autosomal recessive mode of inheritance to assess their phenotype, paraclinical tests, and genotypes. The clinical data encompassed clinical features, the Scale for the Assessment and Rating of Ataxia (SARA) scores, Magnetic Resonance Imaging (MRI) results, Electrodiagnostic exams (EDX), and biomarker features. Our genetic investigations included single-gene testing, Whole Exome Sequencing (WES), and Whole Genome Sequencing (WGS). RESULTS Our study enrolled 162 patients from various geographic regions of our country. Among our subpopulations, we identified known and novel pathogenic variants in 42 genes in 97 families. The overall genetic diagnostic rate was 59.9%. Notably, we observed PLA2G6, ATM, SACS, and SCA variants in 19, 14, 12, and 10 families, respectively. Remarkably, more than 59% of the cases were attributed to pathogenic variants in these genes. CONCLUSIONS Iran, being at the crossroad of the Middle East, exhibits a highly diverse genetic etiology for autosomal recessive hereditary ataxia. In light of this heterogeneity, the development of preventive strategies and targeted molecular therapeutics becomes crucial. A national guideline for the diagnosis and management of patients with these conditions could significantly aid in advancing healthcare approaches and improving patient outcomes.

Abstract
BACKGROUND Diabetic retinopathy (DR) is recognized as one of the most prevalent complications of diabetes and a major cause of morbidity. Transcription factor 7-like 2 (TCF7L2), a pivotal component in the Wnt-signaling pathway, plays a significant role in β-cell development, blood-glucose homeostasis, cell survival, cell migration, and cell proliferation. Thus, this study aimed to assess the association between TCF7L2 variants (rs7903146, rs11196205, and rs12255372) with DR in a population-based association study. MATERIALS AND METHODS DNA was extracted from whole blood of all subjects by salting-out procedure. Total 524 T2DM patients including 234 T2DM individuals without DR and 290 T2DM individuals with DR were genotyped by TaqMan assay technology. Clinical characteristics of subjects were conducted to evaluate the plausible association between TCF7L2 variants and DR with univariate linear regression analysis. RESULTS Demographic analysis between case and control groups revealed significant differences in FBS, HbA1c, lipidemia, heart disease, and family history of T2DM (p < 0.05). No significant difference was observed in either genotypes distribution or allele frequency (p > 0.05) between T2DM individuals with and without DR in any models of inheritance. Genotype-phenotype association showed no significant association. Result of analysis indicated that HbAlc with adjusted OR of 1.8 (p < 0.0001) and first-degree relatives of family history with adjusted OR of 3.04 (p < 0.0001) were significantly associated with DR. Finally, haplotype analysis showed no noticeable association. CONCLUSION In conclusion, there was no significant genetic association between rs7903146, rs11196205, and rs12255372 with DR among T2DM Iranians; however, these variants may play unknown roles in other populations.

Abstract
INTRODUCTION Pompe disease is a lysosomal storage disorder. This study aimed to validate and compare 2 fluorimetric methods for measuring α-glucosidase acid activity in dried blood spot sample (DBS), with potential applications in neonatal screening, and disease follow-up of Pompe patients among the Iranian population for the first time. MATERIALS AND METHODS The evaluation involved 3 enzyme levels and 7 parameters. The analysis included 141 Healthy individuals, 8 Pompe patients, and 10 obligate heterozygotes using reference and modified methods. RESULTS Both methods exhibited highly linear calibration curves. The limit of detection (LOD) and limit of quantification (LOQ) were obtained in the micromolar concentration range in 2 methods. Inter-day and intra-day precision, expressed as relative standard deviations (RSD%) were calculated. The normal ranges were determined in healthy individuals. Receiver operating characteristic (ROC) curves were analyzed, and 2 parameters, total neutral α-glucosidase (NAG)/acid α-glucosidase (GAA) and pH ratio, were identified as cut-off values with excellent accuracy, sensitivity, and specificity for evaluating Pompe disease in both methods. CONCLUSIONS Establishing and implementing these 2 methods for the Iranian population effectively differentiated between healthy and patient individuals. Method II, with its shorter incubation time, demonstrated practicality in the clinical setting.

Abstract
The successful mass-rearing of potential biological control agents is a prerequisite for sustainable pest control. In this study, the performance of 3 Trichogramma euproctidis (Girault) (Hymenoptera: Trichogrammatidae) populations collected from different locations in Khuzestan (Southwest Iran) were evaluated to optimize the egg parasitoid mass-rearing for augmentative biological control of lepidopteran pests. We aimed to investigate the effects of both population origin and host quality on biological traits of ovipositing females (number of parasitized eggs) and of their progeny (development time, survival rate, sex ratio, longevity, and fecundity). The effect of host quality was assessed by allowing the parasitoid to oviposit into 1, 2, 3, or 4-day-old Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) eggs. The 3 T. euproctidis populations developed successfully regardless the age of the host eggs. However, we found significant variation among populations and a strong influence of host quality on the traits investigated. Progeny performance in all populations decreased with increasing host age. The best-performing population (collected in Mollasani) showed the highest parasitization rate, highest survival rate, and progeny sex ratio with the greatest percentage of females. A life table corroborated these findings with superior estimates of the net reproductive rate (R0), intrinsic rate of increase (r), and reduced generation time (T) for the Mollasani population on 1-day-old host eggs. We conclude that ample variation exists among T. euproctidis populations and that rearing the Mollasani population on young rather than old eggs of E. kuehniella would be recommended to implement the biological control programs to target lepidopteran pests in Southwestern Iran.

Abstract
BACKGROUND Human growth hormone (hGH) plays a crucial role in growth by binding to growth hormone receptor (GHR) in target cells. Binding of GH molecules to their cognate receptors triggers downstream signaling pathways leading to the transcription of several genes, including insulin-like growth factor (IGF)-1. Pathogenic variants in the GHR gene can result in structural and functional defects in the GHR protein, leading to Laron Syndrome (LS) with the primary clinical manifestation of short stature. So far, around 100 GHR variants have been reported, mostly biallelic, as causing LS. CASE PRESENTATION We report on three siblings from an Iranian consanguineous family who presented with dwarfism. Whole-exome sequencing (WES) was performed on the proband, revealing a novel homozygous missense variant in the GHR gene (NM_000163.5; c.610 T > A, p.(Trp204Arg)) classified as a likely pathogenic variant according to the recommendation of the American College of Medical Genetics (ACMG). Co-segregation analysis was investigated using Sanger sequencing. CONCLUSIONS To date, approximately 400-500 LS cases with GHR biallelic variants, out of them 10 patients originating from Iran, have been described in the literature. Given the high rate of consanguineous marriages in the Iranian population, the frequency of LS is expected to be higher, which might be explained by undiagnosed cases. Early diagnosis of LS is very important, as treatment is available for this condition.

Abstract
Congenital myasthenic syndromes are inherited disorders caused by mutation in components of the neuromuscular junction and manifest early in life. Mutations in COLQ gene result in congenital myasthenic syndrome. Here, we present the analysis of data from 209 patients from 195 unrelated families highlighting genotype-phenotype correlation. In addition, we describe a COLQ homozygous variant a new patient and discuss it utilizing the Phyre2 and I-TASSER programs. Clinical, molecular genetics, imaging (MRI), and electrodiagnostic (EEG, EMG/NCS) evaluations were performed. Our data showed 89 pathogenic/likely pathogenic variants including 35 missenses, 21 indels, 14 nonsense, 14 splicing, and 5 large deletions variants. Eight common variants were responsible for 48.46% of those. Weakness in proximal muscles, hypotonia, and generalized weakness were detected in all individuals tested. Apart from the weakness, extensive clinical heterogeneity was noted among patients with COLQ-related patients based on their genotypes-those with variants affecting the splice site exhibited more severe clinical features while those with missense variants displayed milder phenotypes, suggesting the role of differential splice variants in multiple functions within the muscle. Analyses and descriptions of these COLQ variants may be helpful in clinical trial readiness and potential development of novel therapies in the setting of established structure-function relationships.

Abstract
Purpose Homeostasis Model Assessment-estimated Insulin Resistance (HOMA-IR) is an important indicator of insulin resistance. In this population-based investigation, we sought to report the mean value of HOMA-IR in different subgroups of a large population-based database of Iranian healthy subjects. Methods This study recruited adult healthy individuals between the ages of 18 to 70 years old to Massoud Medical Laboratory, Tehran, Iran. Fasting insulin was measured by using the Electro Chemiluminescence method using Roche Cobas 6000 e601/602 instrument. Results The mean ± SD value of the HOMA-IR index in the studied population was 2.11 ± 0.99 (2.5-97.5% percentiles: 0.66-4.50). In addition, the mean ± SD of HOMA-IR index in male and female groups were 2.35 1.0 (2.5-97.5 percentile: 0.57-4.37) and 2.05 ± 1.0 (2.5-97.5 percentiles: 0.53-4.35), respectively. Interestingly, it was observed a significant increment for the HOMA-IR index in the male group compared with the female group in all age subgroups (P < 0.01). Conclusions Our findings showed the mean value of 2.11 ± 0.99 HOMA-IR in the Iranian healthy population. Considering the large sample size in our study, more clinical investigations in terms of ethnicity should be done to provide a precise standardized HOMA-IR index in the Iranian population.

Abstract
Background X‐linked mental retardation‐hypotonic facies syndrome‐1 (MRXFH1), caused by a mutation in the ATRX gene, is a rare syndromic form of X‐linked mental retardation (XLMR) that is mainly characterized by severe intellectual disability, dysmorphic facies, and skewed X‐inactivation pattern in carrier women. Method In this study, due to the genetic heterogeneity of the disease, we performed exome sequencing (ES) on a 15‐year‐old boy with primary microcephaly and intellectual disability. Also, Sanger sequencing, cosegregation analysis, and structural modeling were done to identify and verify the causative variant in the proband and other affected individuals in the family. In addition, we collected data from previously reported cases to compare with our patients' phenotypes. Results ES revealed a previously reported missense variant in the ATRX gene (c.5182G > C, p.Ala1728Pro), segregating with the new clinical characteristic including primary microcephaly in the pedigree. This variant meets the criteria of being likely pathogenic based on the ACMG variant interpretation guideline. Conclusions The findings of this study extend the spectrum of phenotypes associated with the identified variant and provide further details on its clinical features.

Abstract
Genetic polymorphisms in cytochrome P450 genes can cause alteration in metabolic activity of clinically important medicines. Thus, single nucleotide variants (SNVs) and copy number variations (CNVs) in CYP genes are leading factors of drug pharmacokinetics and toxicity and form pharmacogenetics biomarkers for drug dosing, efficacy, and safety. The distribution of cytochrome P450 alleles differs significantly between populations with important implications for personalized drug therapy and healthcare programs. To provide a meta-analysis of CYP allele polymorphisms with clinical importance, we brought together whole-genome and exome sequencing data from 800 unrelated individuals of Iranian population (100 subjects from 8 major ethnics of Iran) and 63,269 unrelated individuals of five major human populations (EUR, AMR, AFR, EAS and SAS). By integrating these datasets with population-specific linkage information, we evolved the frequencies of 140 CYP haplotypes related to 9 important CYP450 isoenzymes (CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, CYP3A4 and CYP3A5) giving a large resource for major genetic determinants of drug metabolism. Furthermore, we evaluated the more frequent Iranian alleles and compared the dataset with the Caucasian race. Finally, the similarity of the Iranian population SNVs with other populations was investigated.

Abstract
INTRODUCTION Human papillomavirus (HPV) infection is one of the major health concerns of women in developing countries. This study gives an insight into the prevalence and genotype distribution of HPV infection and compares it with Pap smear results among Iranian women. METHODS In this study, 12,076 Iranian women underwent routine examination from November 2016 to November 2018 using HPV Direct Flow CHIP System for HPV DNA typing. Cytology methods were also undertaken for 5,138 samples. RESULTS Overall HPV prevalence was calculated at 38.68%. The most frequent HPV types were HPV 6, 16, 11, 62/81, 52, and 54, respectively; and, the most high-risk HPV types were HPV 16, 52, 18, 39, 31, and 51. These two groups represent about half of all HPV types detected-47% and 55%, respectively. Among individuals who underwent cytological tests, 135 individuals (2.63%) were cytologically positive. In this group, 81 individuals (60%) were HPV positive as well, 62 (76%) of whom were HR-HPV positive and among them, the most frequent type was HPV 16 (34%). CONCLUSION This study highlights the urgent need for public education and also early diagnosis using HPV screening tests to prevent cervical cancer.

Abstract
Background: Using morphologic features of the bones is the basis of gender determination in anthropology and forensic medicine. In this study, we evaluated the calcaneus diameters for gender determination in the Iranian population.
Methods: This cross-sectional study was conducted on Iranians referring to Hazrat-e Rasool Hospital’s radiology ward for plain lateral X-ray of the foot. Lateral foot X-rays from 100 men and 100 women were gathered and evaluated for calcaneal indexes. These patients aged between 18 and 80 years old who did not suffer major trauma to the calcaneus bone were recruited. Using a picture archiving and communication system (PACS), four variables were calculated for each X-ray graph: Maximum anterior-posterior length of the calcaneus (MAXL), Maximum height of the bone (MAXH), Height of the cuboid facet (CFH) and Height the calcaneal body (BH). Cut off points for each index were calculated using the area under curve (AUC) in ROC curves.
Results: Lateral foot X-rays from 100 men and 100 women were gathered and evaluated for calcaneal indexes. The means of the four indexes were compared between the sexes which showed all four means are significantly different p value <0.001. AUC for MAXL in differentiating the genders was 0.824, which showed 86.8 as the cut off with a sensitivity of 80% and specificity of 69.0%. Cut off point for MAXH was set at 59.8 with sensitivity and specificity of 78.0% and 60.0%, respectively. For BH, 49.5 was set as the cut off point with a sensitivity of 79.0% and specificity of 64.0%. The best cut off point for CFH was 27.8 with 76.0% sensitivity and 63.0% specificity.
Conclusion: It can be concluded that the calcaneal diameters are reliable criteria for sex determination. Although the cutoff points are different between various races and populations, it is evident that these diameters can be used for sex determination in general.

Abstract
PURPOSE The present study was performed to develop the Persian version of food craving inventory (FCI) (FCI-P) and to assess food craving in Iranian adult population. In addition, individual differences, including sex and body mass index (BMI) in food craving were assessed. METHODS Eight hundred and twenty subjects who participated in the same study Hill (Proc Nutr Soc 66: 277-285, 2007) were studied (540 women and 280 men). The FCI-P, International Physical Activity Questionnaire (IPAQ), Three-Factor Eating Questionnaire (TFEQ), and a questionnaire pertaining to demographic characteristics were completed for all participants. RESULTS Good content, construct, and convergent validity was observed for the FCI-P. A good reliability was found for both aggregate scores of the FCI-P and scores of its five factors. Exploratory factor analysis showed a five-factor model including "sweets," "high-fat foods," "fast food fats," "carbohydrates/starches" and "high-fat meats". These five factors accounted for 47.31% of the total variance. The scores of "uncontrolled eating" and "emotional eating" of the TFEQ were significantly correlated with the scores of the FCI-P factors and its total score. A significant correlation was found between BMI and the FCI-P score (r = 0.199). Significant differences were observed in the mean age and physical activity score among normal weight, overweight, and obese participants. Normal weight and overweight groups were more active than obese group. Obese participants had higher FCI-P score (P < 0.001) than the normal and overweight groups. FCI-P score was significantly higher in women than men. CONCLUSIONS FCI-P can be used as a valid and reliable measure to assess food craving in Iranian populations. Obese individuals experienced food craving more than normal weight subjects. Similarly, women may experience food craving more than men. LEVEL OF EVIDENCE Level V, cross sectional study.

Abstract
Objective: Undescended testis (UDT) is a urogenital disease that affects fertility. This study looked into the cytogenetic abnormalities of Iranian infertile patients with UDT. Methods: Our study included 522 infertile patients with UDT (case group) and two control groups, one with 300 infertile men without UDT and another with 268 fertile men. Results: Chromosomal abnormalities were found in 45 patients with UDT (8.62%). Seven of the alterations were considered as normal features. Klinefelter syndrome and mosaicism were the most common anomalies. Chromosomal abnormalities were found in 31 infertile men in the control group (10.33%), 13 of which deemed normal and 18 (6%) anomalous. Nine chromosomal abnormalities were found in the second control group with fertile men (3.35%), six deemed normal and three (1.11%) anomalous. Conclusion: Despite the high rate of abnormalities in infertile controls (6%) and the higher rate seen in infertile individuals with UDT indicate a significant prevalence of chromosomal abnormalities in the Iranian population, particularly when the literature suggests that the normal rate of abnormal karyotypes should be within the 0.7-1% range in the general population. The incidence of abnormal karyotypes increased when infertile patients had additional conditions such as UDT.

Abstract
Objective The current research was conducted to study the association between the SNP309 and del1518 polymorphisms with the breast cancer in the patients with the Kurdish ethnic background from western Iran. Also, a systematic review of the relevant case‐control studies on the MDM2 polymorphisms in the patients with breast cancer was performed. Methodology Two mL of peripheral blood was taken from 100 patients with breast cancer and 100 healthy individuals. The frequencies of MDM2 SNP309 and del1518 genotypes and alleles were determined using the PCR‐RFLP and PCR methods, respectively. Results The frequency of the TT, TG, and GG of MDM2‐SNP309 genotypes in the patients was obtained as 23%, 52%, and 25%, and they were equal to 22%, 40%, and 38% in the control group, respectively. Also, considering the MDM2‐del1518 polymorphism, the frequencies of ins/ins, ins/del, and del/del genotypes were equal to 52%, 41%, and 7% in the breast cancer group and they were equal to 62, 30, and 8% in the control group, respectively. Analysis of the results indicated that the GG genotype plays a protective role for the breast cancer in the recessive model (GG vs TT + TG) of SNP309 (χ2 = 3.916, P = .048, and OR = 0.54). Conclusion Our findings revealed that the GG genotype of MDM2‐SNP309 can play a protective role in the breast cancer disease. Also, our systematic review indicated that the SNP309, SNP285, and del1518 of MDM2 gene in different populations mostly did not have a significant association with the risk of breast cancer.

Abstract
INTRODUCTION Drug dependence and the resultant problems notably decrease the quality of life (QOL). Measuring the QOL in persons who use drugs (PWUDs) and planning to improve it can be helpful for rehabilitation programs. Given the absence of a standard tool to measure the quality of life of PWUD, the present study is an attempt to validate psychometric and cultural characteristics of non-injection drug users' QOL scale. METHOD The study was carried out as a validation and methodological work. The study population consisted of 273 PWUDs in Kermanshah-based drug clinics including outgoing and hospitalized patients. The participants were selected through convenient-quota sampling. After securing the required permission from the copyright owner of the tool, it was forward/backward translated. Face validity and content validity were determined quantitatively and qualitatively. To examine construct validity of the tool, explorative factor analysis and confirmatory factor analysis were used. Internal consistency was measured using Cronbach's alpha and statistical analyses were performed using SPSS (v.25) and LISREL (v.8). RESULTS Explorative factor analysis (EFA) and confirmatory factor analysis (CFA) results supported the tool with one factor and 22 items. The R2 index in the model was equal to 0.99, which means that 99% of the variation of dependent variable (total score of QOL) is attributed to independent variable (22 statements). In other words, 99% of the variation of dependent variable is due to the independent variables in the model. The main indices of the model based on CFA all were higher than 0.9, which indicates goodness of fit of the model (χ2/DF = 2.18, CFI, NFI, TLI = 0.93 GF = 0.84, REMSEA = 0.066, R2 = 0.99). The correlative coefficient was significant (p < 0.05). The reliability of the tool based on internal consistency (Cronbach's alpha) for the subscales ranged from 0.84 to 0.85 and equal to 0.84 for the whole tool. CONCLUSION The Farsi version of non-injection drug users' QOL scale had acceptable indices and it was applicable to assess QOL in the target population. The tool can be used in different fields of drug addiction.

Abstract
There are conflicting results regarding the exact effect of the vitamin D receptor (VDR) gene polymorphisms on the susceptibility to multiple sclerosis (MS). Therefore, we aimed to investigate the impact of four major studied VDR gene polymorphisms consisting of ApaI, BsmI, FokI, and TaqI on the risk of MS in the Iranian population. A literature search was performed in various databases to find case-control studies evaluating the association between VDR gene polymorphisms and MS risk in Iran. Data were extracted and odds ratios (OR) with 95% confidence intervals (CI) were calculated. Subgroup analyze was performed to detect potential sources of heterogeneity. A total of 1206 cases and 1402 controls in nine case-control studies were included. ApaI was the only variant which showed statistically significant relation in allelic (OR = 0.54 (95% CI: 0.37-0.79); P = 0.00), homozygote (OR = 3.48 (95% CI: 1.7-6.9); P = 0.00), dominant (OR = 0.56 (95% CI: 0.3-0.79); P = 0.01), and recessive (OR = 0.35 (95% CI: 0.18-0.66); P = 0.00) models. The TaqI polymorphism showed a significant negative association with MS only in the homozygote model (OR = 0.28 (95% CI: 0.08-0.9); P = 0.04). The BsmI polymorphism also showed significant relation in allelic (OR = 0.69 (95% CI: 0.51-0.94); P = 0.01), homozygote (OR = 0.46 (95% CI: 0.25-0.86); P = 0.01), and recessive OR = 0.56 (95% CI: 0.39-0.8); P = 0.00) models after performing sensitivity analysis. FokI polymorphism showed no significant association with MS risk. ApaI and TaqI TT genotype were found contributing to MS susceptibility and BsmI and FokI showed no relation with MS susceptibility in the Iranian population.

Abstract
BACKGROUND Metabolic syndrome (MetS) is one of the main public health problems worldwide. Although some relations between dietary intakes and MetS have been found, few studies have focused on association between dietary nutrients interactions and the risk of the MetS and its components. The aim of the present study was to examine the association between nutrient patterns and MetS and its components among Iranian adult population. METHODS A total of 588 subjects (aged 18-64 years, 271 males and 317 females) enrolled in the cross sectional study. Dietary consumption was evaluated using an 80-item food frequency questionnaire (FFQ). Biochemical assessments including fasting blood sugar (FBS), aspartate aminotransferase (AST), alanine amino transferase (ALT) and serum lipids were performed by enzymatic methods. Nutrient patterns were obtained by factor analysis procedure using principal component method. Multinational logistic regression analysis was used to evaluate the association between nutrient patterns and MetS and its components. RESULTS Three nutrient patterns explaining 53.66% of the variance in dietary nutrients intake, were recognized in the current study. Animal-sourced nutrient pattern was significantly associated with the higher odds of MetS and high triglyceride (TG) levels. Plant-sourced nutrient pattern (high intake of fiber, carbohydrate, vitamins B6, B3, C, B1, E, D, magnesium, potassium, and linoleic acid) was significantly associated with lower risk of MetS and lower blood pressure (p < 0.05). Third nutrient pattern (mixed-source) was significantly related to higher risk of MetS, high waist circumference (WC) and high systolic blood pressure (SBP). CONCLUSION This present study confirms the important effect of nutrients and their patterns on MetS risk. Our results suggest that adherence to the nutrient pattern rich in fiber, carbohydrate, vitamins D, B6, B3, C, B1, E, magnesium, potassium, linoleic acid, and docosahexaenoic acid (DHA) is associated with a lower risk of MetS, while animal- and mixed-sourced nutrient patterns are positively associated with greater odds of MetS; However, further longitudinal and interventional studies are required to make a clear conclusion.

Background Trabecular bone score (TBS), as a tool for measurement of bone microarchitecture, represents fracture risk independently of bone density. The aim of this study was to estimate the reference values of TBS in both genders among the Iranian population to evaluate osteoporotic fractures in the future. Methods The study was performed on healthy Iranian subjects who live in urban areas of Bushehr city, the capital of Bushehr province in southwestern Iran. The participants in this study were selected through a multistage, age and sex stratified, cluster random sampling. The TBS of L1-L4 was assessed by spine DXA images using TBS iNsight software (Discovery WI, Hologic Inc, USA). Age-related models of TBS were constructed using piecewise linear regression analysis. Results In total, 691 participants aged ≥ 18 years (381 men and 310 women) were selected for the study. The mean and standard deviation (SD) of TBS value for men was 1.420 ± 0.094 and the age at the peak TBS was 30.0 years. Among women, the corresponding value for the mean of TBS was 1.428 ± 0.070 and the age at the peak TBS was 24.5 years. Two SDs below the mean of TBS were 1.326 in men and 1.357 in women. Therefore, the following normal range for TBS values has been proposed: Among men, TBS ≥ 1.326 is considered to be normal; TBS between 1.231 and 1.326 is considered to be partially degraded microarchitecture; and TBS ≤ 1.231defined degraded microarchitecture. Among women, TBS categories are defined as normal ≥ 1.357, partially degraded between 1.287 and 1.357 and degraded ≤ 1.287. Conclusions This was the first study to propose evaluation of the normal range for TBS values in both genders in the Middle- East and Iran. According to our results: TBS ≤ 1.231 in men and TBS ≤ 1.287 in women is considered to be degraded microarchitecture among the Iranian population.

Abstract
BACKGROUND The notable growth of the senior citizens population has caused problems and concerns in areas like healthcare, social care, and participation in society. The present paper is aimed at validating a Farsi version of the "International classification of functioning, disability, and health" for assessing elderly care needs in Kermanshah, Iran. METHODS The original version of the tool was translated into Farsi using forward-backward method. The study group consisted of 301 senior citizens who were selected through cluster sampling. Validity of the tool was examined using Waltz and Basel's content validity index, face validity, and confirmatory factor analysis. The reliability of the tool was examined using Cronbach's alpha and internal correlation. Data analyses were performed in SPSS-25 and Amoss-16. RESULTS Following confirmatory factor analysis, the number of factors decreased from nine to eight. The R2 index in the above model was estimated equal to 0.99; this indicates that 99% of the dependent variable changes (total score of ICF) are explained by the independent variables (eight items). All the indices were above 0.9, which indicates significance of the model (χ2/DF=2.7, CFI, NFI, GFI, TLI=0.9, REMSEA=0.078, R2=0.99). In addition, using internal correlation, the reliability of the tool obtained was equal to 0.77 for the whole tool and 0.7-0.87 for the sub-scales. CONCLUSION The Farsi version of ICF had acceptable and applied specifications to assess the care needs of senior citizens and it can be used as a valid tool in different areas of nursing performance and elderly health.

Abstract
PURPOSE The present study was performed to develop the Persian version of Power of Food Scale (PFS) questionnaire (PFS-P) and to assess the hedonic hunger in Iranian adult population. In addition, associations between individual differences, including sex and body mass index (BMI) and the appetitive motives measured by the PFS-P were assessed. METHODS Eight hundred and twenty participants were studied. The PFS-P, the International Physical Activity Questionnaire, the Three-Factor Eating Questionnaire, and a questionnaire pertaining to demographic characteristics were completed for all participants. RESULTS The Cronbach's alpha values for the factors "food available", "food present" and "food taste" were 0.87, 0.85, and 0.78, respectively. The intraclass correlation coefficient ranged from 0.80 to 0.97 for the factors of PFS-P. Good content, face, criterion, and construct validity were observed for the PFS-P. In addition, a good reliability was found for both aggregate score of the PFS-P and the scores of its three factors. Relatively strong associations were found between BMI and the PFS-P score (r = 0.43). The hedonic hunger was significantly higher in women than men (p < 0.001). CONCLUSIONS The findings of the present study provide further evidence in support of the suitability of PFS as a valid instrument to measure hedonic hunger. PFS-P can be used as a valid and reliable measure to assess hedonic hunger in Iranian populations. In addition, a moderately strong correlation was observed between BMI and hedonic hunger scores. This study revealed that women may experience hedonic hunger more than men. LEVEL OF EVIDENCE Level V, cross-sectional descriptive study.

Abstract
Objective: Pediatric systemic lupus erythematosus (PSLE) is a heterogeneous autoimmune disorder of unknown origin. PTPN22 gene polymorphisms have been associated with SLE in different populations. We investigated the associations of the rs2476601, rs1217414, rs33996649, rs1276457, and rs1310182 SNPs in the PTPN22 gene with PSLE. Materials and methods: 55 PSLE patients and 93 healthy controls were recruited. SNPs were genotyped by the real-time PCR allelic discrimination method. Results: We found that the PTPN22 polymorphisms rs1310182 A allele (p = 0.01, OR = 1.92 95% CI = 1.16-3.18), and rs1310182 AA genotype with (p < 0.001) and rs12760457 TT (p = 0.046) were associated with PSLE. No significant associations were found between other SNPs and PSLE. Conclusions: The PTPN22 rs1310182 A allele and rs1310182 AA genotype were associated with PSLE and may be a possible genetic marker for susceptibility to PSLE. However, further investigation would be required to elucidate the mechanistic role of this association.

Abstract
OBJECTIVE Permanent hypoparathyroidism can be presented as part of genetic disorders such as Sanjad-Sakati syndrome (also known as hypoparathyroidism-intellectual disability-dysmorphism), which is a rare autosomal recessive disorder. Our aim was to confirm the diagnosis of a group of patients with dysmorphism, poor growth, and hypoparathyroidism clinically labeled as Sanjad-Sakati syndrome and to identify for the first time the genetic variations on Iranian patients with the same ethnic origin. METHODS In this study, 29 cases from 23 unrelated Arab kindreds with permanent hypoparathyroidism and dysmorphism indicating Sanjad-Sakati syndrome were enrolled for 10 years in the southwest of Iran. The mutational analysis by direct sequencing of the tubulin folding cofactor E gene was performed for the patients and their families, as well as their fetuses using genomic DNA. RESULTS Twenty-eight out of 29 cases had parental consanguinity. Twenty-seven cases presented with hypocalcemia seizure and two were referred because of poor weight gain and were found to have asymptomatic hypocalcemia. The dysmorphic features, hypocalcemia in the setting of low to normal parathyroid hormone levels and high phosphorus led to the diagnosis of these cases. Sequencing analysis of the tubulin folding cofactor E gene revealed a homozygous 12-bp deletion (c.155-166del) for all patients. Following that, prenatal diagnosis was performed for eight families, and two fetuses with a homozygous 12-bp deletion were identified. CONCLUSION These results make it much easier and faster to diagnose this syndrome from other similar dysmorphisms and also help to detect carriers, as well as prenatal diagnosis of Sanjad-Sakati syndrome in high-risk families in this population.

Abstract
OBJECTIVES The genetics of sensorineural hearing loss is characterized by a high degree of heterogeneity. In spite of this, mutations in the SLC26A4 gene, have been reported to be the second most common contributor after those of GJB2 in many populations. However, different results have been reported for the frequency of SLC26A4 mutations in Iran, which varies between 0 and 12.3%. Here, we have taken together and reviewed the spectrum and frequency of the reported SLC26A4 mutations to provide a comprehensive collection of data for SLC26A4 mutations and HL in the Iranian population and considered founder mutations. METHODS A systematic literature review of the PubMed, Google Scholar, Web of Science, and Science Direct databases was conducted for articles published before March 2019. The primary data of these studies including the number of samples, mutation frequency and so on were extracted. RESULTS Nine studies involved 827 unrelated families were included and analyzed for the type and prevalence of the SLC26A4 gene mutations. Altogether 39 different genetic mutations were detected. SLC26A4 mutations were found to be 6.39% in the population studied which is significantly lower than that identified in the east Asia. However, c.1334T > G was the most common mutation accounting for 10% of the populations studied. CONCLUSIONS This data gives an overview of the SLC26A4 mutations in Iran, which could be used for screening, diagnostic programs of live births and genetic counseling.

Abstract
Polymorphisms of vitamin D receptors (VDRs), ApaI, BsmI, FokI, and TaqI might affect susceptibility to tuberculosis (TB). In this systematic review and meta-analysis, all published articles which investigated the effects of these polymorphisms on the risk of TB in the Iranian population were retrieved. PubMed and Scopus were searched with no date or language restrictions. In this meta-analysis, the Comprehensive Meta-Analysis (CMA) version 2.0 and random effects model were applied. The association of polymorphisms with TB risk was assessed by measuring the odds ratio (ORs) at 95% CI. Heterogeneity was investigated based on Cochran Q-test and I2-index statistics. The significance level was set at 0.05. Also, Egger's regression intercept was determined to measure publication bias. A total of six articles on Iranian populations were included. TaqI (5/6 included studies) showed a significant association with the increased risk of TB based on ORs (allele comparison: 1.57 (1.0, 2.3), p-value: 0.02; additive model of tt/TT: 1.57 (0.9, 2.5), p-value: 0.05; recessive model (tt/Tt + TT): 1.99 (1.2, 3.2), p-value: 0.00; dominant model (tt + Tt/TT): 1.98 (1.1, 3.5), p-value: 0.01). BsmI showed a significant positive effect on TB risk only in its dominant genotype (bb + bB/BB) (1.44 (1.0, 1.9); p-value: 0.02). FokI and ApaI did not show any significant effects on TB development in Iranian populations. Findings showed the significant effect of TaqI polymorphism in all genetic models and the dominant model of BsmI on the increased risk of TB. However, the effects of TaqI and BsmI should be further investigated in a larger sample size.

Abstract
Mutations in the GJB2 gene are a main cause of autosomal-recessive nonsyndromic hearing loss (ARNSHL) in many populations. Previous studies have estimated the average frequency of GJB2 mutations to be ∼16% in Iran, but would vary among different ethnic groups. Here, we have taken together and reviewed results from our two previous publications and data from searching other published mutation reports to provide a comprehensive collection of data for GJB2 mutations and HL in central Iran. In all, 332 unrelated families were included and analyzed for the prevalence and type of the GJB2 gene mutations. In total, the frequency of GJB2 mutations was found to be 16% in the central provinces, which is significantly higher than those identified in southern populations of Iran. Also, c.35delG was the most frequent mutation in the related population. The present study suggests that mutations in the GJB2 gene, especially c.35delG, are important causes of HL in central Iran and can be used as a basis of genetic counseling and clinical guidelines in this region.

Abstract
Background Mucopolysaccharidosis type I (MPSI) is a rare autosomal recessive disorder caused by a deficiency of α‐l‐iduronidase (IDUA) encoded by the IDUA gene. We examined the mutation spectrum of the IDUA gene to explain the clinical, biochemical, and molecular features in 21 Iranian patients with MPSI. Methods Sanger sequencing was used to measure the IDUA gene sequence in the coding region and exon‐intron boundaries. We recorded the clinical findings of studied patients at the first diagnosis of disease and then during the treatment and follow‐up. Results Five different missense disease‐causing mutations were determined in our patient groups, indicating 90.48% of detection rate. The most widespread mutation was the p.Y109H, occurring in 15.625% of all alleles, which was reported for the first time in our study. Other frequent mutations were as follows: p.Ser157Pro (12.5%), p.Gly84Arg (12.5%), p.Asp257His (9.375%), and p.Asp301Glu (9.375%). Three ones of them were new missense mutations: p.Ser157Pro, p.Asp257His, and p.Asp301Glu. Discussion The results of this study explain the different spectrum of IDUA gene mutations in our patients with MPSI. We introduced here 32 different variants including four new variants: p.Y109H (15.625%), p.S157P (12.5%), p.D257H (9.375%), and p.D301E (9.375%). In this series, there was no relationship between the happening of clinical features and genotype variations and biochemical findings.

Abstract
Mutations in the GJB2 gene are the most common cause of pre-lingual hearing loss (HL) worldwide. Previous studies have shown the frequency of GJB2 mutations to be 16% in Iran, but varies among different ethnic groups. Here, we have reviewed results from previous published mutation reports to provide a comprehensive collection of data for GJB2 mutations and HL in eastern Iran. We conducted a systematic literature review of PubMed, Google Scholar, Web of Science, and Science Direct databases for articles published before March, 2019. The literature search was performed by 2 independent researchers. The primary data of these studies including the number of samples, allelic frequency, and so on were extracted. Six studies involving 812 unrelated families from four different eastern provinces were included and analyzed for the type and prevalence of GJB2 mutations. A total of 19 different genetic variants were detected. GJB2 mutations were 8.8% in the studied eastern provinces, which was lower than that reported in northern populations of Iran. Moreover, a gradient in the frequency of GJB2 mutations from north to south Iran was observed. c.35delG was the most frequent mutation, accounting for 48.5% % of the populations studied. However, this mutation was absent in the Baluchi population. This review shows that particular rare mutations are frequent in some Iranian ethnic groups, and should be considered for genetic counselling.

Abstract
INTRODUCTION Voice disorders can affect the quality of life and coping mechanisms and also coping mechanisms can affect the way in which patients deal with their voice problems. People with voice disorders need to use coping strategies to deal with the problems caused by their voice disorder. The purpose of this study was to examine the psychometric properties and cultural adaptation of the Voice Disability Coping Questionnaire in the Iranian population. METHODS The translation and cross-cultural adaptation procedures were performed according to the basic rules and instructions set by the International Quality of Life Assessment Project. Two hundred and forty-eight adults (218 patients with voice disorder and 30 healthy controls) were participated in the study. Face and content validity, clinical validity, and construct validity of the questionnaire were investigated by modern psychometric methods. RESULTS Quantitative methods were used to measure content validity and all items were detected applicable. This means that the final version was clear and easy to answer. Clinical validity shows that the Persian version of VDCQ can distinguish between patients and healthy controls (P < 0.001). The construct validity of the VDCQ was tested in a cross-sectional study. The questionnaire was analyzed by exploratory and confirmatory factor analyses. Investigation of initial communality and after extraction of factors by Varimax rotation method showed that the share of items for all items in the questionnaire except item 12, is higher than 0.5. Therefore, item 12 should be removed from the questionnaire (Table 3). Based on the confirmatory factor analysis model, items 2 and 10, whose factor load were less than 0.4, were excluded from the questionnaire (Fig. 1). For reliability the Cronbach's alpha coefficient and ICC were obtained as 0.82 and 0.99, respectively. The results of studying the role of items in the reliability of the VDCQ showed that all items increase internal consistency. CONCLUSION Based on modern statistical analysis conducted in this study, the original 15 item questionnaire was reduced to 12 item. The 12 item questionnaire is a valid and reliable tool for quantifying coping strategies in people with voice disorder.

Abstract
Background: Phospholipase C epsilon 1 (PLCE1) gene harbors different single nucleotide polymorphisms (SNPs), which can be correlated with the risk of different types of cancers. In this case-control study, the relationship between rs2274223 (A>G), a single nucleotide polymorphism in phospholipase C epsilon gene, (PLCE1) and gastric cancer was evaluated among Iranian patients. Materials and Methods: The PLCE1 rs2274223 polymorphism was genotyped in 60 patients with gastric cancer and 69 control subjects using polymerase chain reaction and restriction fragment length polymorphisms (PCR-RFLP) methods. Clinical and pathologic parameters such as tumor characteristics and disease stage were also recorded. Results: There were 48 (80%) male patients and 45 (65.5%) healthy male individuals (p=0.077). About 34 (56.6%) patients were smokers. A family history of gastric cancer was found in 21 (35%) cases. GG genotype was observed among 15% of patients and 8.7% of normals, respectively. There was no significant difference between the AA and AG genotypes. Also, there were no significant correlations between AA, AG or GG genotypes and the risk of gastric cancer, gender, tumor size, tumor stage, grade, as well as tumor location and metastasis. Conclusion: The PLCE1 rs2274223 polymorphism was not correlated with gastric cancer in Iranian population. However, a further comprehensive study with larger sample sizes is needed.

Abstract
OBJECTIVES To determine the association between ERAP2 rs2549782 and rs17408150 polymorphisms and pre-eclampsia among Iranian women. METHODS A retrospective case-control study comparing 319 women with pre-eclampsia and 291 normotensive pregnant Iranian women between January and August 2016. Pre-eclampsia was diagnosed by the International Society for the Study of Hypertension in Pregnancy's criteria. Demographic data were collected by oral interview. Genotyping was done by allele-specific PCR. Data were analyzed using SPSS v. 16. RESULTS The frequency of the rs2549782TT genotype was 31.0% and 27.5% among cases and controls, respectively (P=0.006). There was no difference in the frequency of the T allele between groups (P>0.05). Regarding the rs17408150 polymorphism, a high portion of women with pre-eclampsia was homozygous for the AA genotype (P<0.001). The frequency of the A allele was 32.5% and 25.05% among cases and controls, respectively (P=0.004). The combined haplotype of the rs2549782A and rs17408150G alleles was associated with increased risk of pre-eclampsia (P=0.031). CONCLUSION ERAP2 gene polymorphisms were associated with the risk of pre-eclampsia in an Iranian population. The results provide further evidence of the role of ERAP2 in the pathophysiology of this disease.

Abstract
OBJECTIVE Mutations in the GJB2 gene are a major cause of autosomal recessive non-syndromic HL (ARNSHL) in many populations. Previous studies have estimated the average frequency of GJB2 mutations to be between 16 and 18% in Iran, but would vary among different ethnic groups. Here, we have taken together and reviewed results from our three previous publications and data from search other published mutation reports to provide a comprehensive collection of data for GJB2 mutations and HL in the south of Iran. METHODS In all, 447 unrelated families were included and analyzed for the prevalence and type of the GJB2 gene mutations. RESULTS Totally, the frequency of GJB2 mutations was found to be 11.5% in the southern provinces studied which is significantly lower than that identified in Northern populations of Iran, and also a southwest to southeast Iranian gradient in the frequency of GJB2 mutations is suggested. CONCLUSIONS This study highlights the importance of establishing prevalence, based on the local population for screening and diagnostic programs of live births in Iran.

Abstract
BACKGROUND Hearing loss (HL) is the most prevalent sensory disorder. The over 100 genes implicated in autosomal recessive nonsyndromic hearing loss (ARNSHL) makes it difficult to analyze and determine the accurate genetic causes of hearing loss. We sought to de?ne the frequency of seven hearing loss-Causing causing genetic Variants in four genes in an Iranian population with hearing loss. MATERIALS AND METHODS One hundred ARNSHL patients with normal GJB2/GJB6 genes were included, and targeted mutations in SLC26A4, MYO6, PJVK and CDH23 genes were analyzed by ARMS-PCR. The negative and positive results were confirmed by the Sanger sequencing. RESULTS We found only two mutations, one in MYO6 (c.554-1 G > A) gene and another in PJVK (c.547C > T). CONCLUSION c.554-1G > A and c.547C > T mutations are responsible for 1% each of the Iranian ARNSHL patients. These genes are not a frequent cause of ARNSHL in an Iranian population.

Abstract
Methylmalonic acidemia (MMA), an inherited metabolic disease, results from genetic defects in methylmalonyl-CoA mutase or any of the proteins involved in adenosylcobalamin synthesis. This enzyme is classified into several complementation groups and genotypic classes. In this work we explain the biochemical, structural and genetic analysis of 25 MMA patients, from Iran. The diagnosis was established by the measurement of propionylcarnitine in blood using tandem mass spectrometry and confirmed using a gas chromatography-flame ionization detector. Using clinical, biochemical, structural and molecular analyses we identified 15 mut MMA, three cblA, one cblB, and four cblC-deficient patients. Among mutations identified in the MUT gene (MUT) only one, the c.1874A>C (p.D625A) variant, is likely a mut- mutation. The remaining mutations are probably mut0. Here, we present the first molecular analysis of MMA in Iranian patients and have identified eight novel mutations. Four novel mutations (p.D625A, p.R326G, p.V157F, p.F379L) were seen exclusively in patients from northern Iran. One novel splice site mutation (c.2125-3C>G) in MUT and two novel mutation (p.N225M and p.A99P) in the MMAA gene were associated with patients from eastern Iran. The rs184829210 SNP was recognized only in patients with the novel c.958G>A (p.A320T) mutation. This study confirms pathogenesis of deficient enzyme activity in MUT, MMAA, MMAB, and MMACHC as previous observations. These results could act as a basis for the performance of pharmacological therapies for increasing the activity of proteins derived from these mutations.

Abstract
OBJECTIVE Hereditary hearing loss is the most common neurosensory disorder in humans caused by myriad mutations in numerous genes. Autosomal recessive nonsyndromic hearing loss (ARNSHL) accounts for 80% of hearing impairments of genetic origin and is quite prevalent in societies with a high rate of consanguinity. In the current study, we investigated the causes of sensorineural hearing loss in 24 unrelated Iranian families who were mainly consanguineous and had at least two affected children. METHODS All probands were initially screened for GJB2 mutations, as the most common causes of ARNSHL in Iran. Verified GJB2-negative samples were subsequently subjected to whole exome sequencing (WES) to identify the underlying causes of hearing impairment, and the variants identified in each family were further confirmed by Sanger sequencing. RESULTS WES revealed three previously unreported mutations in MYO15A, the gene encoding the unconventional myosin 15 (Myo15). All variants identified, c.C6436T (p.R2146W), c.C9584G (p.P3195R) and c.G10266C (p.Q3422H), reside in the MYTH4 (myosin tail homology) and FERM (4.1 ezrin, radixin, moesin) domains of the protein. CONCLUSION Globally, mutations in MYO15A are considered to be among the most prevalent genetic causes of ARNSHL, and they rank as the third leading cause of hearing loss in the Iranian population, below GJB2 and SLC26A4. Yet again, these results endorse the importance of MYO15 screening in hearing impaired populations, particularly in Iran.

Abstract
Background As the total hip arthroplasty (THA) mainly aims to improve the quality of life of the patients, study of health-related quality of life (HRQoL) after THA has attracted much attention. Yet, the results considerably vary between studies. Here, we evaluate the HRQoL of the patient after THA, for the first time in the Iranian population. Methods In a case-control study, HRQoL was assessed in 217 patients after THA and compared with a matched reference population. The 36-item short-form health survey (SF-36) was used for the evaluation of HRQoL. A multiple linear regression model was used to investigate the influence of sociodemographic and clinical characteristics of the patients on the HRQOL. Results The mean follow-up of the patients was 27 ± 18 months. The mean total SF-36 score was 41.4 ± 22.2 in the case and 67.3 ± 26.6 in the control group (p = 0.001). The mean physical component score, but not the mental component score, was significantly lower in the patient group (p = 0.001). Except for the vitality and emotional role, all other SF-36 subscales were significantly lower in the case group. Male sex (B = 4.52, p = 0.023), number of comorbidities (B = − 4.82, p = 0.011), body mass index (B = − 1.18, p = 0.044), number of post-operative complications (B = − 6.57, p = 0.001), and adherence to physiotherapy protocol (B = 2.09, p = 0.014) were associated with HRQoL after THA. Conclusion Although THA is considered as one of the most successful orthopedic practices, it is associated with remarkable reduced HRQoL in Iranian population when compared with the reference population. A variety of patients-associated factors influence the HRQoL after THA.

Abstract
Background We aimed to determine the promoter methylation status of the retinoic acid receptor-beta 2 (RARβ2) gene among breast cancer patients and to review relevant studies in this field in various populations. Methods We analyzed 400 samples which comprised blood specimens from 102 breast cancer patients, 102 first-degree female relatives of patients, 100 cancer-free females, 48 breast cancer tissues, and 48 adjacent normal breast tissues from the same patients. The RARβ2 methylation status was determined using methylation-specific polymerase chain reaction (MSP) and DNA sequencing methods. Results The presence of combined partially methylated (MU) and fully methylated (MM) forms of the RARβ2 gene (MU+MM) in the blood of patients was associated with susceptibility to breast cancer (odds ratio = 4.7, p = 0.05). A significantly higher frequency of the MM genotype was observed in cancer tissue (10.4%) compared to matched adjacent normal breast tissue (0%) (p = 0.02). Conclusion We found a higher frequency of RARβ2 gene methylation in the blood and cancer tissues of patients compared to the blood of controls and adjacent normal breast tissues. The survey of studies on various populations demonstrated a higher RARβ2 methylation frequency in breast cancer patients compared to normal individuals, and many reports suggest a significant association between hypermethylation of the gene and susceptibility to breast cancer.

Abstract
BACKGROUND Based on lack of data on the distribution of the related alleles in the T1D population in Iranian population, we assessed the frequency of HLA DQ2 and DQ8 haplotypes in patients with T1D with/without CD compared to healthy population. MATERIALS AND METHODS 70 patients with T1D without celiac disease, 60 T1D cases with CD were compared to 150 healthy individuals during 2016. Ten mililiter Gheparinized blood samples were collected, genomic DNA was extracted and alleles were genotyped by Real-time PCR using SYBR Green as a low-resolution method. RESULTS HLA-DQ2 and/or HLA-DQ8 genotypes was presented in 51% and 23% of T1D patients without CD respectively. Twenty one percent of those patients carried both alleles and 5% were negative for both alleles. T1D patients with CD had much higher DQ2 frequency (72%) and lower DQ8 (11.6%), than T1D patients without CD and controls, 14% carried both alleles and 3% were negative for both. The frequencies of DQ2 and DQ8 alleles in Iranian healthy population were 19 and 5% respectively. CONCLUSION According to the same genetic background for CD and T1D we suggest that HLA-typing can be a very useful screening tool for CD in patients with type one diabetes.

Abstract
Numerical variation in α-globin genes is very important due to their roles as an effective factor for phenotype presentation. An unequal crossover from misalignment of a homologous sequence of an α-globin gene during meiosis can produce a numerical alteration. A single α-globin gene deletion is the most frequent mutation in α-thalassemia (α-thal) worldwide, while the additional α-globin chain is relatively common. The excess α-globin gene plays a critical role in pathophysiology of thalassemia, especially when in coinherited with β-thalassemia (β-thal). α-Globin triplication leads to an imbalanced ratio between α- and β-globin chains, thus, it can exacerbate the clinical and hematological features of β-thal. Different studies have been performed in various countries to determine the frequency of α-globin triplication and its genotype-phenotype correlation with β-thal. In this study, we focused on the frequency of α-globin gene triplication and its characterization, either solely or in coexistence with β-globin gene mutations in Iranian populations. We have investigated the α-globin gene rearrangements in 4010 individuals from different provinces of Iran with normal to abnormal hematological parameters. In total, the frequency of the αααanti 3.7 triplication was 1.7% and phenotype aggravation was observed in α-globin triplication patients who were carriers of β-thal. Therefore, identification of genotype-phenotype correlation of α-globin triplication with β-thal can be very useful for predicting the severity of clinical manifestations during genetic counseling.

Abstract
Phenylketonuria (PKU) is a metabolic disorder caused by mutations in the phenylalanine hydroxylase (PAH) gene. After thalassemia, PKU is considered as the most common autosomal recessive diseases in the Iranian population. Therefore, an efficient diagnostic strategy is required to identify disease-causing mutations in this population. Following our first report in 2003, here we presented a comprehensive study on the mutation spectrum of the PAH gene in the Iranian population. This study was performed on 280 unrelated chromosomes from 140 Iranian patients with classic PKU. All 13 exons as well as exon-intron boundaries of the PAH gene were analyzed by direct DNA sequencing. Thirty four different mutations were identified by a mutation detection rate of 100%. IVS10-11G > A, p.P281L, R261Q, p.F39del and IVS11+1G > C were the most prevalent mutations with frequencies of 26.07%, 19.3%, 12.86%, 6.07 and 3.93%, respectively. All other mutations represented a relative frequency less than 3.5%. The data from this study provided a comprehensive spectrum of the PAH gene mutations which can facilitate carrier detection and prenatal diagnosis of PKU disease in the Iranian population.

Abstract
BACKGROUND The Lifestyle Promotion Project (LPP) is a long-term community-based project for prevention and control of non-communicable diseases (NCDs). In this project, the healthy lifestyle promotion plan will be implemented by the health policy agenda of East Azerbaijan Province, Iran. METHODS The study design included two phases: phase I was a cross-sectional prevalence study of NCDs and the associated risk factors implemented from Feb 2014 to Apr 2014. Phase II is a prospective follow-up study currently ongoing. The healthy lifestyle promotion intervention consists of five core strategic plans. These programs was implemented by the health policy agenda of East Azerbaijan Province. Overall, 3000 participants aged 15-65 yr were enrolled to evaluate the impact of healthy lifestyle interventions in phase II of project. RESULTS The experience of the LPP in Iran may support the idea that a well-organized, fully evidence-based, and well-developed community-based program could be affordable to prevent non-communicable disorders in developing countries. CONCLUSION The results of this survey will be presented as research articles and reports for policy makers.

Abstract
OBJECTIVE Inborn errors of metabolism (IEMs) are disorders with various manifestations that occur mainly in the pediatric population. In countries where consanguineous marriage is common, the association between consanguinity and IEMs is highly important. No studies have been conducted in Iran examining the impact of consanguinity on IEMs. METHODS In this retrospective study, the incidences of metabolic disorders were evaluated for the years 2006 through 2016 in the North East Iran Regional Diagnostic Laboratory (Pardis Clinical and Genetic Laboratory). A total of 13,327 infants with clinical symptoms were referred and investigated for IEMs. Newborn screening was performed on samples from all patients suspected of having IEMs. RESULTS Of 13,327 infants examined, 60 different IEMs were diagnosed in 1,118. The most frequent disorders among our patients were glucose-6-phosphate dehydrogenase deficiency (G6PDD) (14.04%), methylmalonic and propionic acidurias (MMA/PA) (9.12%), phenylketonuria (PKU) (8%), and isovaleric acidemia (IVA) (6.98%). A significant difference was found in the prevalence of amino acid disorders between the offspring of consanguineous and those of non-consanguineous parents. No statistically significant differences were found between the 2 groups for organic or fatty acids, carnitine or urine cycles, or lysosomal storage disorders. A total of 707 of the 1,118 infants with metabolic diseases (63.24%) were children of consanguineous parents. These findings show that consanguinity can be an important factor in the inheritance of recessive mutations in a homozygous state. CONCLUSION This study found a greater frequency of metabolic diseases in offspring of consanguineous parents than in those of non-consanguineous parents in a population with a high rate of consanguinity.

Abstract
The interaction of FAS/FAS ligand (FASL) serves an important role in the upregulation of apoptotic processes through different mechanisms in cells. Previous studies have established that the polymorphisms FAS-670A/G and FASL-844C/T are associated with risk of generalized aggressive periodontitis (GAP) in different ethnic populations. Therefore, in the present study, it was investigated for the first time whether FAS-670A/G and FASL-844C/T polymorphisms were associated with risk of GAP in Iran. This case-control study performed the polymerase chain reaction-restriction fragment length polymorphism method in 25 patients with GAP and 110 normal subjects as controls. The results indicated that there was no significant difference in FAS-670A/G genotype frequency between the GAP and control groups. A higher frequency of the combined genotype (AG+GG) was observed in the GAP patients (96.0%) compared with the control subjects (90.9%), though this was not significant [χ2=0.705, degrees of freedom (df)=1, P=0.401]. Similarly, the prevalence of the G allele was non-significantly higher in the GAP group (62.0%) compared with that in the controls (60.0%; χ2=0.012, df=1, P=0.913). For FASL-844C/T polymorphism, the frequency of the combined genotype (CT+TT) was higher in the GAP group (96.0%) when compared with the control subjects (91.8%); however its association was not statistically significant (χ2=0.519, df=1, P=0.471). The frequency of the T allele only marginally differed between the groups, being 60.0% in the GAP group and 50.9% in the controls (χ2=3.627, df=1, P=0.057). These results indicated that there were no significant associations between the FAS-670A/G and FASL-844C/T polymorphisms and the risk of disease in GAP patients when compared with normal individuals.

Abstract
BACKGROUND MYBPC3 mutations have been described in dilated cardiomyopathy (DCM) and hypertrophic cardiomyopathy (HCM). A mutation, c.3373G>A, has been reported to cause autosomal recessive form of HCM. Here, we report that this mutation can cause autosomal dominant form of DCM. METHODS Next-generation sequencing using targeted panel of a total of 23 candidate genes and following Sanger sequencing was applied to detect causal mutations of DCM. Computational analyses were also performed using available software tools. In silico structural and functional analyses including protein modeling and prediction were done for the mutated MYBPC3 protein. RESULTS AND CONCLUSION Targeted sequencing showed one variant c.3373G>A (p.Val1125Met) in the studied family following autosomal dominant inheritance. Computational programs predicted a high score of pathogenicity. Secondary structure of the region surrounding p.Val1125 was changed to a shortened beta-strand based on prediction of I-TASSER and Phyre2 servers with high confidence value for the mutation. cMyBP-C protein was modeled to 3dmkA. Our findings suggest that one single mutation of MYBPC3 may have different effects on the cellular mechanisms based of its zygosity. Various factors might be considered for explaining this phenomenon. This gene may have an important role in Iranian DCM and HCM patients.

Abstract
Objective: Acute brain injury is one of the leading causes of morbidity and mortality worldwide. Phenytoin has been commonly used as an anticonvulsant agent for the treatment or prophylaxis of seizures following acute brain injury. After a severe head injury, several pharmacokinetic changes occur. The aim of this study is the comparative evaluation of phenytoin serum concentration in patients with traumatic and nontraumatic brain injury (TBI). Methods: This prospective observational study was performed on twenty adult brain injury patients who were admitted to an Intensive Care Unit and required phenytoin for the treatment or prophylaxis of postinjury seizures. For all the patients, phenytoin serum concentration was determined in three scheduled time points. Phenytoin serum concentration and pharmacokinetic parameters were compared between patients with TBI and cerebrovascular accident (CVA). Findings: The Vmaxand Kmwere significantly higher in head trauma (HT) patients than the CVA group. The phenytoin concentration (Cp) and the Cp/dose ratio were significantly higher in the CVA group patients during the first sampling (P < 0.05). The Acute Physiology and Chronic Health Evaluation П (APACHE П) score was significantly lower than the baseline at the end of the study in each group of patients (P < 0.05). In addition, no significant correlation was observed between Vmax, Km, Cp, Cp/dose ratio, and APACHE II scores at the time of sampling. Conclusion: Due to significant differences in phenytoin plasma concentration and pharmacokinetic parameters between HT and CVA patients, close attention must be paid to the pharmacokinetic behavior of phenytoin in the efforts to improve the patient's outcome after a severe HT.

Abstract
T-cell immunoglobulin and mucin domain (TIM)-3 have been shown to negatively regulate Th1 cell-mediated immunity. Activation of TIM-3 by galectin-9 induces Th1 cell apoptosis, which may contribute to skewing of immune response towards Th2-dominant immunity. The aim of this study was to determine whether certain genetic variations of TIM-3 influence predisposition to asthma in a sample of Iranian population. This case-control study was conducted on 209 patients with asthma and 200 healthy controls. The +4259 T>G and -574 G>T polymorphisms were detected using polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) and amplification refractory mutation system-PCR(ARMS-PCR). Total serum IgE was further measured with ELISA. Notably, +4259T > G and-574G>T polymorphisms of TIM-3 were significantly associated with the susceptibility to asthma. In addition, the present study showed a significant difference between the distribution frequency of the GT + TT genotype and T allele on the +4259 T>G and -574 G>T locus between the groups.However, no correlation between the +4259 T > G and -574G > T polymorphisms and total serum IgE levels were observed. Together these results suggest that the TIM-3 +4259 T>G and -574 G>T polymorphisms are greatly associated with the susceptibility of Iranian population to asthma, which could open up new horizons for better understanding of the pathophysiology, diagnostic, prognostic and therapeutic approaches of asthma.

Abstract
BACKGROUND Data concerning the association of serum levels of vitamin D and metalloproteinases and vitamin D receptor gene polymorphism with coronary artery disease (CAD) is not fully demonstrated. The present study aimed to evaluate the association of vitamin D receptor gene polymorphism, serum levels of 25(OH) vitamin D and metalloproteinase-9 (MMP-9) with CAD. METHODS 104 patients with CAD and 69 Non-CAD subjects were included in current study. Vitamin D receptor genotypes were determined by PCR-RFLP method. The 25(OH) vitamin D and MMP-9 were determined by ELISA assay. RESULTS There was a significant reduction of vitamin D in CAD patients (P=0.001). The metalloproteinase 9 levels of CAD patient was increased significantly compared with controls (P=0.001). A significant reverse correlation also was found between MMP-9 concentration and 25(OH) vitamin D levels of patients (r=-0.28, P<0.001). In addition, we identified that VDR gene FokI polymorphism was significantly associated with CAD. Furthermore, MMP-9 levels of CAD patients with ff genotype of FokI polymorphism was higher significantly than patients with FF and Ff genotypes. It has been also found that MMP-9 levels of CAD patients with ff genotype of FokI polymorphism was higher significantly than patients with FF and Ff genotypes. CONCLUSION Our results indicated that 25(OH) vitamin D, MMP-9 levels and VDR gene FokI polymorphisms play a critical role in the development and progression of CAD and may contribute to susceptibility to CAD in Iranian populations.

Abstract
OBJECTIVES An important domain in health-related quality of life evaluations is quality of life perceptions due to having a voice disorder. The purpose of the current study was (1) to examine the correlation of the Iranian Voice Quality of Life Profile (IVQLP) with the Voice-Related Quality of Life (VRQOL) and Voice Handicap Index-30 (VHI-30) for establishing the construct convergent validity of the IVQLP, and (2) to examine the correlation between VRQOL and VHI-30. METHODS Study sample consisted of 150 patients, 91 male and 59 female, diagnosed with muscle tension dysphonia, benign organic disorders such as polyps and nodules, and unilateral vocal fold paralysis. In total, 150 patients aged 46.53 ± 13.84 years completed the IVQLP and Persian versions of the VHI and VRQOL. RESULTS The results showed that Spearman rank-order correlation coefficient between the results of the VHI and IVQLP questionnaires was 0.90 (P < 0.001). The correlation coefficient between VRQOL and IVQLP was -0.88. (P < 0.001) The Spearman correlation between VHI and VRQOL was -0.94. (P < 0.001) CONCLUSIONS: The current study showed that the IVQLP has good construct validity, and it can evaluate quality of life in Iranian dysphonic patients based on their culture. Also, the VHI-30 and VRQOL correlation was very high.

Abstract
BACKGROUND Hypospadias is one of the most common forms of congenital malformation of the male external genitalia worldwide. The ratio in the Iranian population is one in 250 live male births. The conversion of testosterone to dihydrotestosterone (DHT) in the presence of steroid 5α-reductase 2, which is encoded by SRD5A2 gene, plays an important role in the normal development of the male reproductive system. METHODS We examined whether SRD5A2 gene mutations (V89L and A49T polymorphisms) are associated with the risk of hypospadias in the Iranian population. We performed exons sequencing for SRD5A2 gene in 109 hypospadias patients. RESULTS We identified two new mutations in the subgroups of affected cases: including a substitution of the nucleotide T > A in the codon 73 [c.219T > A (p.Leu73_Ser74insHisPro)] and an insertion of an extra A nucleotide in the codon 77 [c.229insA* (p.Gly77*)]. Additionally, we performed PCR-RFLP for the two identified polymorphisms and revealed that V89L [OR = 5.8, 95% CI (3.8-8.8), p value < 0.001] and A49T [OR = 10.16, 95% CI (3.94-26.25), p value < 0.001] are significantly associated with hypospadias occurrence in patients. Our haplotype analysis further indicated that the Leu-Ala haplotype increases risk of hypospadias; conversely, the Val-Ala haplotype decreases the risk of hypospadias in the studied patients. CONCLUSIONS This study demonstrates that polymorphisms in the SRD5A2 gene could be considered as a risk factor for hypospadias disease emergence.

Abstract
Multiple sclerosis (MS) is one of the most common diseases of the central nervous system (CNS) in the Iranian population. To date, association of many genes with the prevalence and progression of the disease have been investigated. In the present study, the impact of rs1738074 single nucleotide polymorphism (SNP) in the TAGAP gene (TAGAP rs1738074) on the risk of MS was evaluated in a sample of the Iranian population. In a case control study, genotyping was performed on 300 patients and normal individuals. The data were analyzed using Pearson's chi-square test. The results showed a significant difference in the SNP frequency between case and control groups (p-value=0.049). The genotype frequencies of TT, TC and CC in patients were 10.67%, 51.33% and 38%, respectively, and in normal individuals were 20.66%, 42.67% and 36.67%, respectively. The results showed a significant difference in the genotype frequency of T/T between the patient and control groups (p<0.05). Interestingly, individuals with T/T genotype were estimated to be less susceptible to MS ((p-value=0.025), Fisher's exact test), odd ratio was 2.18 (controls versus MS patients) with 95% CI: 1.137-4.187. The results suggested that TAGAP rs1738074 polymorphism could be considered as a risk factor in the prevalence of MS in the Iranian population.
