Abstract
PURPOSE The purpose of this study was to determine the point prevalence (PP) of general pressure injuries (PIs), hospital-acquired PIs, PI-related risk factors, and PI preventive interventions performed by nurses. DESIGN Descriptive, multicenter, prospective, analytical study. SUBJECTS AND SETTING The sample comprised 5088 patients cared for in 13 hospitals in 12 geographic regions of Turkey. Data were collected between November 5, 2018, and July 17, 2019. METHODS The study was carried out in 2 stages. First, nurses who collected data were trained in the diagnosis of PI, risk assessment, staging, and prevalence studies, and informed about the purpose and methods of the study, including data collection. Second, nurses and researchers who had received training related to data collection for this study conducted a PP study for PIs in their inpatient clinics using the ASSIST II method. The PI Prevalence Study Tool and the Braden Scale for Predicting Pressure Sore Risk were also used during data collection. RESULTS The PP of general PIs was 9.5%; the prevalence of PIs with hospitalization in intensive care units was 43.2%; medical device-related pressure injuries prevalence was 10.7%. We found that 65.1% of the PIs were acquired after hospital admission. CONCLUSIONS Similarities exist between PI prevalence in Turkey and reported PI prevalence rates worldwide. However, the prevalence of nosocomial PIs related to intensive care units and the prevalence of all nosocomial injuries were higher than rates previously reported. Based on results, there is a need to develop strategies to reduce the prevalence of nosocomial PIs.

Abstract
PURPOSE Brain monoamine vesicular transport disease is an infantile-onset movement disorder that mimics cerebral palsy. In 2013, the homozygous SLC18A2 variant, p.Pro387Leu, was first reported as a cause of this rare disorder, and dopamine agonists were efficient for treating affected individuals from a single large family. To date, only 6 variants have been reported. In this study, we evaluated genotype-phenotype correlations in individuals with biallelic SLC18A2 variants. METHODS A total of 42 affected individuals with homozygous SLC18A2 variant alleles were identified. We evaluated genotype-phenotype correlations and the missense variants in the affected individuals based on the structural modeling of rat VMAT2 encoded by Slc18a2, with cytoplasm- and lumen-facing conformations. A Caenorhabditis elegans model was created for functional studies. RESULTS A total of 19 homozygous SLC18A2 variants, including 3 recurrent variants, were identified using exome sequencing. The affected individuals typically showed global developmental delay, hypotonia, dystonia, oculogyric crisis, and autonomic nervous system involvement (temperature dysregulation/sweating, hypersalivation, and gastrointestinal dysmotility). Among the 58 affected individuals described to date, 16 (28%) died before the age of 13 years. Of the 17 patients with p.Pro237His, 9 died, whereas all 14 patients with p.Pro387Leu survived. Although a dopamine agonist mildly improved the disease symptoms in 18 of 21 patients (86%), some affected individuals with p.Ile43Phe and p.Pro387Leu showed milder phenotypes and presented prolonged survival even without treatment. The C. elegans model showed behavioral abnormalities. CONCLUSION These data expand the phenotypic and genotypic spectra of SLC18A2-related disorders.

Abstract
AIM This study was conducted to determine the impact of tailored training provided to nurses for preventing pressure injuries (PIs) on nurses' knowledge levels and the PI point prevalence (PP). MATERIALS AND METHODS This interventional study was carried out in a university hospital with a bed capacity of 1114 in an urban center in Turkey. Ethics committee approval (28.06.2018/31) and institutional permission were obtained for the study, in addition to the nurses' written, informed consent. The study was completed in three stages. In the first stage an initial PP study was conducted in the clinics with the participation of the nurses and the members of the research team (n = 422 patients). In the second stage the knowledge levels of 194 nurses were measured before training was given on following-up and preventing PIs. The nurses then participated in the tailored training and their knowledge levels were re-measured afterwards. All the nurses were given individual advice related to the prevention of PIs for 30 days after they had completed the training. In the third stage a second PP study was conducted four months after the first PP study (n = 454 patients). The data were collected using the Pressure Injury Prevalence Form, the Braden Pressure Ulcer Risk Assessment Tool and the Knowledge Level Measurement Form. Descriptive values, the paired samples t-test, Pearson's chi-squared test and Fisher's Exact test were used to evaluate the data. RESULTS The nurses' pretest mean knowledge score was 55.36% ± 14.40 and their posttest mean score was 69.92% ± 9.73. The difference between these scores was statistically significant (p < 0.05). The study found no significant difference between the first PP ratio and the second PP ratio (p > 0.05), and the nurses were better able to evaluate skin and PIs after the training. CONCLUSION The study determined that the tailored training given to the nurses increased their knowledge; however, it had no impact on the PP after four months. It is recommended that any training programs using this model be continued and that PP studies of institutions be conducted annually.

Abstract
IMPORTANCE Exfoliation syndrome is a systemic disorder characterized by progressive accumulation of abnormal fibrillar protein aggregates manifesting clinically in the anterior chamber of the eye. This disorder is the most commonly known cause of glaucoma and a major cause of irreversible blindness. OBJECTIVE To determine if exfoliation syndrome is associated with rare, protein-changing variants predicted to impair protein function. DESIGN, SETTING, AND PARTICIPANTS A 2-stage, case-control, whole-exome sequencing association study with a discovery cohort and 2 independently ascertained validation cohorts. Study participants from 14 countries were enrolled between February 1999 and December 2019. The date of last clinical follow-up was December 2019. Affected individuals had exfoliation material on anterior segment structures of at least 1 eye as visualized by slit lamp examination. Unaffected individuals had no signs of exfoliation syndrome. EXPOSURES Rare, coding-sequence genetic variants predicted to be damaging by bioinformatic algorithms trained to recognize alterations that impair protein function. MAIN OUTCOMES AND MEASURES The primary outcome was the presence of exfoliation syndrome. Exome-wide significance for detected variants was defined as P < 2.5 × 10-6. The secondary outcomes included biochemical enzymatic assays and gene expression analyses. RESULTS The discovery cohort included 4028 participants with exfoliation syndrome (median age, 78 years [interquartile range, 73-83 years]; 2377 [59.0%] women) and 5638 participants without exfoliation syndrome (median age, 72 years [interquartile range, 65-78 years]; 3159 [56.0%] women). In the discovery cohort, persons with exfoliation syndrome, compared with those without exfoliation syndrome, were significantly more likely to carry damaging CYP39A1 variants (1.3% vs 0.30%, respectively; odds ratio, 3.55 [95% CI, 2.07-6.10]; P = 6.1 × 10-7). This outcome was validated in 2 independent cohorts. The first validation cohort included 2337 individuals with exfoliation syndrome (median age, 74 years; 1132 women; n = 1934 with demographic data) and 2813 individuals without exfoliation syndrome (median age, 72 years; 1287 women; n = 2421 with demographic data). The second validation cohort included 1663 individuals with exfoliation syndrome (median age, 75 years; 587 women; n = 1064 with demographic data) and 3962 individuals without exfoliation syndrome (median age, 74 years; 951 women; n = 1555 with demographic data). Of the individuals from both validation cohorts, 5.2% with exfoliation syndrome carried CYP39A1 damaging alleles vs 3.1% without exfoliation syndrome (odds ratio, 1.82 [95% CI, 1.47-2.26]; P < .001). Biochemical assays classified 34 of 42 damaging CYP39A1 alleles as functionally deficient (median reduction in enzymatic activity compared with wild-type CYP39A1, 94.4% [interquartile range, 78.7%-98.2%] for the 34 deficient variants). CYP39A1 transcript expression was 47% lower (95% CI, 30%-64% lower; P < .001) in ciliary body tissues from individuals with exfoliation syndrome compared with individuals without exfoliation syndrome. CONCLUSIONS AND RELEVANCE In this whole-exome sequencing case-control study, presence of exfoliation syndrome was significantly associated with carriage of functionally deficient CYP39A1 sequence variants. Further research is needed to understand the clinical implications of these findings.

Abstract
Members of a paralogous gene family in which variation in one gene is known to cause disease are eight times more likely to also be associated with human disease. Recent studies have elucidated DHX30 and DDX3X as genes for which pathogenic variant alleles are involved in neurodevelopmental disorders. We hypothesized that variants in paralogous genes encoding members of the DExD/H-box RNA helicase superfamily might also underlie developmental delay and/or intellectual disability (DD and/or ID) disease phenotypes. Here we describe 15 unrelated individuals who have DD and/or ID, central nervous system (CNS) dysfunction, vertebral anomalies, and dysmorphic features and were found to have probably damaging variants in DExD/H-box RNA helicase genes. In addition, these individuals exhibit a variety of other tissue and organ system involvement including ocular, outer ear, hearing, cardiac, and kidney tissues. Five individuals with homozygous (one), compound-heterozygous (two), or de novo (two) missense variants in DHX37 were identified by exome sequencing. We identified ten total individuals with missense variants in three other DDX/DHX paralogs: DHX16 (four individuals), DDX54 (three individuals), and DHX34 (three individuals). Most identified variants are rare, predicted to be damaging, and occur at conserved amino acid residues. Taken together, these 15 individuals implicate the DExD/H-box helicases in both dominantly and recessively inherited neurodevelopmental phenotypes and highlight the potential for more than one disease mechanism underlying these disorders.

Abstract
BACKGROUND Niemann-Pick disease Type C (NP-C) is a rare, autosomal recessive lysosomal storage disorder caused by mutations in NPC1 or NPC2 genes. Diagnosis of NP-C can be challenging and is frequently delayed. Identifying mutations in individuals with NP-C and their relatives enables genetic counseling and prenatal diagnosis and may support earlier diagnosis. Here we report findings from a prospective cohort study in Turkey, using targeted genetic screening of the families of NP-C probands with homozygous NPC1 or NPC2 mutations. METHODS Probands were selected from a Turkish National Registration Database. Probands had confirmed diagnosis based on NPC1 or NPC2 mutations, with clear indication for consanguineous, homozygous inheritance. Family members were identified from interviews and pedigree analysis. Genetic analysis was performed on DNA from peripheral blood samples from all subjects. RESULTS Four probands and 510 individuals from the four families were included. In these four families, the overall NPC1 or NPC2 heterozygous mutation frequency was 22.7%. A novel mutation was identified in NPC1 (p.T375P; c.1123A>C). A previously described NPC2 mutation (p.E118X; c.352G>T) was also observed in two families from different regions of Turkey. We identified two new patients with NP-C from two families. CONCLUSIONS This is the largest screening study conducted to date in Turkey in the families of patients with NP-C with homozygous inheritance. We have reported heterozygote frequencies, identified a novel mutation, and detected new patients with NP-C. These findings will aid our understanding of NP-C and may lead to improved recognition and more timely diagnosis.

Abstract
Exfoliation syndrome (XFS) is the most common known risk factor for secondary glaucoma and a major cause of blindness worldwide. Variants in two genes, LOXL1 and CACNA1A, have previously been associated with XFS. To further elucidate the genetic basis of XFS, we collected a global sample of XFS cases to refine the association at LOXL1, which previously showed inconsistent results across populations, and to identify new variants associated with XFS. We identified a rare protective allele at LOXL1 (p.Phe407, odds ratio (OR) = 25, P = 2.9 × 10-14) through deep resequencing of XFS cases and controls from nine countries. A genome-wide association study (GWAS) of XFS cases and controls from 24 countries followed by replication in 18 countries identified seven genome-wide significant loci (P < 5 × 10-8). We identified association signals at 13q12 (POMP), 11q23.3 (TMEM136), 6p21 (AGPAT1), 3p24 (RBMS3) and 5q23 (near SEMA6A). These findings provide biological insights into the pathology of XFS and highlight a potential role for naturally occurring rare LOXL1 variants in disease biology.

Abstract
Tremendous progress in genetics and genomics led to a wide range of healthcare providers, genetic tests, and more patients who can benefit from these developments. To guarantee and improve the quality of genetic testing, a unified European-based registration for individuals qualified in biomedicine was realized. Therefore a Europe-wide recognition of the profession ‘European registered Clinical Laboratory Geneticist (ErCLG)' based on a syllabus of core competences was established which allows for harmonization in professional education. The ‘European Board of Medical Genetics division − Clinical Laboratory Geneticist' provides now since 3 years the possibility to register as an ErCLG. Applicants may be from all European countries and since this year also from outside of Europe. Five subtitles reflect the exact specialty of each ErCLG, who can reregister every 5 years. A previously not possible statistics based on ~300 individuals from 19 countries as holders of an ErCLG title provides interesting insights into the professionals working in human genetics. It could be substantiated that there are around twice as many females than males and that a PhD title was achieved by 80% of registered ErCLGs. Also most ErCLGs are still trained as generalists (66%), followed by such ErCLGs with focus on molecular genetics (23%); the remaining are concentrated either on clinical (6%), tumor (4%) or biochemical genetics (1%). In conclusion, besides MDs and genetic counselors/nurses an EU-wide recognition system for Clinical Laboratory Geneticist has been established, which strengthens the status of specialists working in human genetic diagnostics in Europe and worldwide.

Abstract
Reported here are twins, both of whom have a 1q21.3 microdeletion and who exhibit key features common to previously reported cases such as microcephaly and developmental delay. However, some clinical findings and deleted genes differed from those in previously reported cases. The karyotype was normal 46, XX for both of the twins. Array comparative genomic hybridization (CGH) identified a 2.6 Mb deletion on chromosome 1q21.3 (chr1: 153,514,121-156,171,335 bp) in case 1 and a 1.6 Mb deletion on chromosome 1q21.3 (chr1: 154,748,365-156,358,923 bp) in case 2. The deleted region includes DPM3, MUC1, GBA, PKLR, RIT1, and LAMTOR2 in both siblings. To the extent known, this is the second report of a 1q21.3 microdeletion in a family with mental retardation, developmental delay, seizures, and some dysmorphic features, thus expanding the phenotypic spectrum.

Abstract
We report an efficient energy-time entangled photon-pair source based on four-wave mixing in a CMOS-compatible silicon photonics ring resonator. Thanks to suitable optimization, the source shows a large spectral brightness of 400 pairs of entangled photons /s/MHz for 500 μW pump power, compatible with standard telecom dense wavelength division multiplexers. We demonstrate high-purity energy-time entanglement, i.e., free of photonic noise, with near perfect raw visibilities (> 98%) between various channel pairs in the telecom C-band. Such a compact source stands as a path towards more complex quantum photonic circuits dedicated to quantum communication systems.

Abstract
The 17q21.31 microdeletion syndrome is characterized by intellectual disability, epilepsy, facial dysmorphism and friendly behavior. Recently, KANSLJ gene has been considered as a major causal gene for this phenotype. Here we report on two Turkish patients with different seizure types and additional dysmorphic features associated with 17q21.31 microdeletion syndrome. A 4 year-old female patient with generalized tonic-clonic seizures, mild mental retardation, dysmorphic features and friendly behavior and a 14 years-old female with intractable epilepsy, different dysmorphic features, severe mental and motor retardation and self-mutilation were evaluated by array-based comparative genomic hybridization (microarray CGH). Array CGH identified 17q21.31 microdeletion that contains MAP7 CRHR1, KANSLI, PLEKHMI genes in case I and CRHR1, PLEKHM but not KANSLJgenes in case 2. To the best of our knowledge this is the first report of a patient with the 17q21.31 microdeletion which does not encompass KANSLI gene. These data imply another gene or genes causing similar phenotype in this patient.

Abstract
The body image perceptions of persons with a stoma and their partners are rarely examined and have yet to be evaluated in a Turkish sample. Using convenience sampling methods, a descriptive, cross-sectional study was conducted among individuals receiving treatment at the authors' stomatherapy unit between March 1, 2012 and May 31, 2012 to assess the effect of the stoma on self-image and partner perception. Eligible participants had to be >18 years of age, married, and with an abdominal stoma (colostomy, urostomy, or ileostomy) for at least 2 months. Data were obtained through separate (patient or partner), face-to-face, 30-minute to 45-minute interviews using the appropriate questionnaire. Questionnaire items assessed demographic variables and patient/partner feelings toward the ostomate's body using the Body Cathexis Scale (BCS) and author-developed questionnaires comprising statements eliciting individual responses (agree, disagree, undecided) regarding their feelings toward the stoma. Data were tabulated and analyzed using percentile distributions, and Mann Whitney U and Kruskal Wallis H tests were performed (Bonferroni correction was applied). Sixty (60) patients (25 women, 35 men, mean age 56.01 ± 10.1 years; 25 with an ileostomy, 30 with a colostomy, 5 with an ileostomy) participated, along with their 60 heterosexual partners (mean age 54.56 ± 10.25 years) married a mean of 33.06 ± 11.03 years. Mean patient BCS score was 133.15 ± 20.58 (range 40--low perception--to 200--high perception). Mean BCS score of patients whose partner helped in stoma care was significantly higher (136.04) than those whose partners did not (120.27) (P = 0.033). Patients who consulted their partners' opinions on stoma creation and participation in care had significantly higher BCS scores (P <0.05), and BCS scores of patients whose partners thought the stoma had a negative effect on their relationship were significantly lower (P = 0.040); patients' perceptions toward their bodies were parallel to their partners'. Mean BCS score of patients experiencing physical and psychosocial problems was significantly lower than those of patients who did not experience such problems. The results of this study show a number of factors, including involving patient partners before surgery, affect body perception of persons following stoma surgery.

Abstract
Background Complex small supernumerary marker chromosomes (sSMC) constitute one of the smallest subgroups of sSMC in general. Complex sSMC consist of chromosomal material derived from more than one chromosome; the best known representative of this group is the derivative chromosome 22 {der(22)t(11;22)} or Emanuel syndrome. In 2008 we speculated that complex sSMC could be part of an underestimated entity. Results Here, the overall yet reported 412 complex sSMC are summarized. They constitute 8.4% of all yet in detail characterized sSMC cases. The majority of the complex sSMC is contributed by patients suffering from Emanuel syndrome (82%). Besides there are a der(22)t(8;22)(q24.1;q11.1) and a der(13)t(13;18)(q11;p11.21) or der(21)t(18;21)(p11.21;q11.1) = der(13 or 21)t(13 or 21;18) syndrome. The latter two represent another 2.6% and 2.2% of the complex sSMC-cases, respectively. The large majority of complex sSMC has a centric minute shape and derives from an acrocentric chromosome. Nonetheless, complex sSMC can involve material from each chromosomal origin. Most complex sSMC are inherited form a balanced translocation in one parent and are non-mosaic. Interestingly, there are hot spots for the chromosomal breakpoints involved. Conclusions Complex sSMC need to be considered in diagnostics, especially in non-mosaic, centric minute shaped sSMC. As yet three complex-sSMC-associated syndromes are identified. As recurrent breakpoints in the complex sSMC were characterized, it is to be expected that more syndromes are identified in this subgroup of sSMC. Overall, complex sSMC emphasize once more the importance of detailed cytogenetic analyses, especially in patients with idiopathic mental retardation.

Abstract
GRID2 is a member of the ionotropic glutamate receptor family of excitatory neurotransmitter receptors. GRID2 encodes the glutamate receptor subunit delta-2, selectively expressed in cerebellar Purkinje cells. The phenotype associated with loss of GRID2 function was described only in mice until now, characterized by different degrees of cerebellar ataxia and usually relatively mild abnormalities of the cerebellum. This work describes for the first time the human phenotype associated with homozygous partial deletion of GRID2 in 3 children in one large consanguineous Turkish family. Homozygous deletion of exons 3 and 4 of GRID2 (94 153 589-94 298 037 bp) in the proband and similarly affected cousins, and heterozygous deletions in parental DNA were shown using Affymetrix® 6.0 single-nucleotide polymorphism array, confirmed by real-time polymerase chain reaction. The phenotype includes nystagmus, hypotonia with marked developmental delay in gross motor skills in early infancy followed by a static encephalopathy course with development of cerebellar ataxia, oculomotor apraxia, and pyramidal tract involvement.

Abstract
We present the electroclinical features and cytogenetic findings of 2 siblings with the ring 20 chromosome (r(20)) phenotype, one of which had r(20) mosaicism. A history of epilepsy or learning problems should be determined in family members, although these relatives had no ring formation in chromosome 20. Whether the clinical features result from possible deletions or ring formation is discussed.

Abstract
Inherited severe hypoplasminogenaemia is a multisystemic disorder leading to deficient extravascular fibrinolysis. As a clinical consequence wound healing capacity of mucous membranes is markedly impaired leading to ligneous conjunctivitis and several other manifestations. Here we report the molecular genetic and clinical findings on 23 new cases with severe hypoplasminogenaemia. Homozygous or compound-heterozygous mutations in the plasminogen (PLG) gene were found in 16 of 23 patients (70%), three of which were novel mutations reported here for the first time (C166Y, Y264S, IVS10-7T/G). Compared to 79 previously published cases, clinical manifestations of the current group of patients showed higher percentages of ligneous periodontitis, congenital hydrocephalus, and involvement of the female genital tract. In contrast, involvement of the gastrointestinal or urogenital tract was not observed in any of the cases. Patients originated to a large extent (61%) from Turkey and the Middle East, and showed a comparably frequent occurrence of consanguinity of affected families and a greater female to male ratio than was derived from previous reports in the literature. Individual treatment of ligneous conjunctivitis included topical plasminogen or heparin eye drops, topical or systemic fresh frozen plasma, and surgical removal of ligneous pseudomembranes, mostly with modest or transient efficacy. In conclusion, the present study underscores the broad range of clinical manifestations in PLG-deficient patients with a trend to regional differences. Transmission of genetic and clinical data to the recently established Plasminogen Deficiency Registry should help to determine the prevalence of the disease and to develop more efficient treatment strategies.

Abstract
Background Genomic imbalances constitute a major cause of congenital and developmental abnormalities. GLUT1 deficiency syndrome is caused by various de novo mutations in the facilitated human glucose transporter 1 gene (1p34.2) and patients with this syndrome have been diagnosed with hypoglycorrhachia, mental and developmental delay, microcephaly and seizures. Furthermore, 1q terminal deletions have been submitted in the recent reports and the absence of corpus callosum has been related to the deletion between C1orf100 and C1orf121 in 1q44. Results This study reports on a sibling pair with developmental delay, mental retardation, microcephaly, hypotonia, epilepsy, facial dysmorphism, ataxia and impaired speech. Chromosome analysis revealed a derivative chromosome 1 in both patients. FISH and MCB analysis showed two interstitial deletions at 1p34.2 and 1q44. SNP array and array-CGH analysis also determined the sizes of deletions detailed. The deleted region on 1p34.2 encompasses 33 genes, among which is GLUT1 gene (SLC2A1). However, the deleted region on 1q44 includes 59 genes and distal-proximal breakpoints were located in the ZNF672 gene and SMYD3 gene, respectively. Conclusion Haploinsufficiency of GLUT1 leads to GLUT1 deficiency syndrome, consistent with the phenotype in patients of this study. Conversely, in the deleted region on 1q44, none of the genes are related to findings in these patients. Additionally, the results confirm previous reports on that corpus callosal development may depend on the critical gene(s) lying in 1q44 proximal to the SMYD3 gene.

Abstract
We present an autosomal-recessive frontonasal dysplasia (FND) characterized by bilateral extreme microphthalmia, bilateral oblique facial cleft, complete cleft palate, hypertelorism, wide nasal bridge with hypoplasia of the ala nasi, and low-set, posteriorly rotated ears in two distinct families. Using Affymetrix 250K SNP array genotyping and homozygosity mapping, we mapped this clinical entity to chromosome 12q21. In one of the families, three siblings were affected, and CNV analysis of the critical region showed a homozygous 3.7 Mb deletion containing the ALX1 (CART1) gene, which encodes the aristaless-like homeobox 1 transcription factor. In the second family we identified a homozygous donor-splice-site mutation (c.531+1G > A) in the ALX1 gene, providing evidence that complete loss of function of ALX1 protein causes severe disruption of early craniofacial development. Unlike loss of its murine ortholog, loss of human ALX1 does not result in neural-tube defects; however, it does severely affect the orchestrated fusion between frontonasal, nasomedial, nasolateral, and maxillary processes during early-stage embryogenesis. This study further expands the spectrum of the recently recognized autosomal-recessive ALX-related FND phenotype in humans.

Abstract
Osteogenesis imperfecta is a clinically and genetically heterogeneous brittle bone disorder that results from defects in the synthesis, structure, or posttranslational modification of type I procollagen. Dominant forms of OI result from mutations in COL1A1 or COL1A2, which encode the chains of the type I procollagen heterotrimer. The mildest form of OI typically results from diminished synthesis of structurally normal type I procollagen, whereas moderately severe to lethal forms of OI usually result from structural defects in one of the type I procollagen chains. Recessively inherited OI, usually phenotypically severe, has recently been shown to result from defects in the prolyl-3-hydroxylase complex that lead to the absence of a single 3-hydroxyproline at residue 986 of the alpha1(I) triple helical domain. We studied a cohort of five consanguineous Turkish families, originating from the Black Sea region of Turkey, with moderately severe recessively inherited OI and identified a novel locus for OI on chromosome 17. In these families, and in a Mexican-American family, homozygosity for mutations in FKBP10, which encodes FKBP65, a chaperone that participates in type I procollagen folding, was identified. Further, we determined that FKBP10 mutations affect type I procollagen secretion. These findings identify a previously unrecognized mechanism in the pathogenesis of OI.

Abstract
Wilms tumor (WT) is the most common primary renal tumor in childhood. The occurrence of WT in patients with growth retardation, mental retardation and central nervous system abnormalities in association with premature chromatid separation (PCS) and mosaic variegated aneuploidy has been previously described in only 10 patients. Here we report the very rare occurrence of WT with two other malignancies, acute myeloid leukemia and medulloblastoma in association with chromosomal instability. This is a novel presentation of Fanconi anemia with this cytogenetic abnormality.

Abstract
Background Because of low copy repeats (LCRs) and common inversion polymorphisms, the human chromosome 8p is prone to a number of recurrent rearrangements. Each of these rearrangements is associated with several phenotypic features. We report on a patient with various clinical malformations and developmental delay in connection with an inverted duplication event, involving chromosome 8p. Methods Chromosome analysis, multicolor banding analysis (MCB), extensive fluorescence in situ hybridization (FISH) analysis and microsatellite analysis were performed. Results The karyotype was characterized in detail by multicolor banding (MCB), subtelomeric and centromere-near probes as 46,XY,dup(8)(pter->p23.3::p12->p23.3::p23.3->qter). Additionally, microsatellite analysis revealed the paternal origin of the duplication and gave hints for a mitotic recombination involving about 6 MB in 8p23.3. Conclusion A comprehensive analysis of the derivative chromosome 8 suggested a previously unreported mechanism of formation, which included an early mitotic aberration leading to maternal isodisomy, followed by an inverted duplication of the 8p12p23.3 region.

Abstract
Thirty-two patients with fertility problems were identified as carriers of small supernumerary marker chromosomes (sSMC). Molecular cytogenetic techniques were used to characterize their chromosomal origin. Together with the other cases available in the literature 111 sSMC cases have now been detected in connection with fertility problems in otherwise clinically healthy persons and characterized for their genetic content. According to this study, in 60% of the cases the sSMC originated from chromosomes 14 or 15. Euchromatic imbalances were caused by the sSMC presence in 30% of the cases. Notably, in 53% of infertile sSMC carriers, the sSMC was parentally transmitted. As we found indications of an as yet unknown mechanism for the elimination of sSMC from the human gene pool, sSMC could also play a role in elucidating the process of chromosome gain and loss during evolution. Nonetheless, further detailed molecular analysis will be necessary in the future to characterize the mechanisms and genetic basis for this phenomenon.

Abstract
We report on two cases with partial trisomy 1q syndrome. One case was a mid-trimester fetus with multiple malformations that was prenatally diagnosed with a de novo distal partial trisomy 1q. Prenatal ultrasound at 24th gestational week demonstrated the presence of cleft lip and palate, increased biparietal diameter and decreased abdominal circumference. Cytogenetic analysis (GTG banding) and subsequent fluorescence in situ hybridization (FISH) using whole chromosome paint 1 and multicolor banding (MCB) demonstrated an aberrant karyotype 46,XY,dup(1)(q31q43 approximately 44). The second case was a newborn male infant with multiple congenital malformations. He had a derivative chromosome 18 as a result of a maternal insertion involving chromosomes 1 and 18. Further analyses including MCB showed his karyotype as 46,XY,ins(18;1)(q22;q23q31.1 approximately 32). The present cases and a review of the literature suggest that partial trisomy of the long arm of chromosome 1 is a distinct clinical entity.

Abstract
Here we report on three new patients with neocentric small supernumerary marker chromosomes (sSMC) derived from chromosome 2, 13 and 15, respectively. The sSMC(13) and sSMC(15) had inverted duplicated shapes and the sSMC(2) a ring chromosome shape. All three cases were clinically severely abnormal. A review of the available sSMC literature revealed that up to the present 73 neocentric sSMC cases including these three new cases have been reported. Seven of these cases were not characterized morphologically; in the remainder, 80% had an inverted duplication, 17% a ring and 3% a minute shape. 81% of the reported neocentric sSMC carriers showed severe, 12% moderate and 8% no clinical abnormalities. In summary, we report three more neocentric sSMC cases, provide a review on all up to now published cases, highlight their special characteristics and compare them to centric sSMC.

Abstract
Uveal melanoma is the most common primary intraocular malignancy in adults. Several cytogenetic studies on uveal melanoma cells have revealed that the majority of these cells harbor alterations in chromosomes 3, 6, and 8. This report describes the results of cytogenetic analysis performed on a fresh choroidal melanoma tissue sample from a patient with cerebellar metastasis. Monosomy 7 mosaicism was observed. To our knowledge, monosomy 7 has not been reported in patients with uveal melanoma. We suggest that observation of monosomy 7 may be related to an aggressive clinical behavior and unusual cerebellar metastasis in uveal melanoma. Further data are necessary to define the exact role of monosomy 7 in the pathogenesis and evolution of uveal melanoma.

Abstract
Periventricular nodular heterotopia (PNH) is a rare neuronal migration disorder in which immature neurons fail to undergo a directed migration from the ventricular and subventricular zones to the cerebral cortex. Classic PNH occurs predominantly in females and is associated with periods of epilepsy and near-normal intelligence. One gene associated with PNH was mapped to chromosome Xq28. PNH with learning disability is reported in 15 male patients with several syndromes and various congenital abnormalities such as craniosynostosis, frontonasal malformation, and agenesis of the corpus callosum. We present a 26-year-old male patient who was followed up with the diagnosis of epilepsy from the age of 1 year. Additionally the patient had severe learning disability, obesity, and hypogonadism. Imaging of his brain demonstrated PNH. Klinefelter syndrome was clinically suspected, and analysis of his chromosomes revealed a karyotype 46,XY,der(19)t(X;19) (q11.1-11.2;p13.3). Molecular techniques, such as subtelomere-specific fluorescent in-situ hybridization and multicolour banding, were also used. The same translocation was demonstrated in his mother and his maternal grandmother. This family might help to explain the gene localization of X-linked recessive PNH. In our patient, PNH is associated with familial (X;19) translocation. To our knowledge, this unique combination has not been reported in the medical literature.

Abstract
Fragile X syndrome (FXS) is a well-recognized mental retardation syndrome with characteristic facial features and behavioural phenotype. Monosomy 21 is a rare cytogenetic aberration for which clinical features were incompletely defined since full monosomy 21 is incompatible with life. A 5-year-old male patient with FXS and low-grade mosaicism for full monosomy 21 (46,XY[96%]/45,XY,-21[4%]) is presented. He had lack of speech and severely impaired social skills, hyperactivity, stereotypical hand movements, a special interest towards moving colourful items and a short attention span for other objects around. He had macrocephaly, a rather long face, prominent occiput and prominent midface, retrognathia, down-slanting palpebral fissures, hypertelorism and cup-shaped, posteriorly rotated and low-set ears. Full monosomy in the aberrant cell line was proven by whole chromosome painting. FXS was previously reported to accompany sex chromosome aneuploidies; however, to the best of our knowledge, the present patient is the first FXS patient with an aberration involving autosomes. He contributes to the current knowledge on monosomy 21 phenotype, having dysmorphic facial findings despite the concurrent phenotypic expression of the FXS. As a last conclusion, cytogenetic analysis must be done to all mentally retarded patients with minor dysmorphic features.

Abstract
Goldenhar syndrome (GS) or oculoauriculovertebral dysplasia (OAVD) is characterized by pre-auricular skin tags, microtia, facial asymmetry, ocular abnormalities and vertebral anomalies of different size and shape. The phenotypical findings of this syndrome are variable due to heterogenous aetiology. For that reason, the physician sometimes faces difficulty when making a definite diagnosis of OAVD. We reviewed the clinical and laboratory findings of 31 patients (15 boys and 16 girls) aged from 1 day to 16 years with the clinical diagnosis of GS. The characteristic features were pre-auricular skin tags (90%), microtia (52%), hemifacial microsomia (77%) and epibulbar dermoids (39%). Vertebral anomalies were noted in 70% of the patients. Cardiac malformations were found in 39% while a genitourinary anomaly was noted in 23% and various central nervous system malformations in 47%. There were 3 pregnancies following an intracytoplasmic sperm injection (ICSI) technique among the 31 patients. Two patients with GS came from the same family. Their relatives had hydrocephaly, myelomeningocele and neural tube defects. It is known that some chromosomal aberrations are seen in GS. We performed chromosome analysis of 29 patients. Among these cases, only one patient with severe mental and motor retardation had a 47,XX,+der(22)t(11,22)(q23; q11 karyotype due to a maternal balanced translocation t(11;22)(q23;q11). This translocation was demonstrated in her sister, brother and maternal uncle. Additionally CATCH 22 analysis in 13 cases with OAVD with a CATCH 22 phenotype revealed no deletion. OAVD patients present with different morphologic features and systemic manifestations. A multidisciplinary approach should be undertaken by departments such as pediatric cardiology, audiology, ophthalmology and plastic surgery when evaluating patients with OAVD. Chromosome analysis should be performed in every patient with Goldenhar syndrome.

Abstract
Myelodysplastic syndrome (MDS) is a clonal hematopoietic stem cell disorder characterized by ineffective hematopoiesis, peripheral cytopenia, and dysplastic changes in the bone marrow. Monosomy 7 or partial loss of 7q is a common cytogenetic abnormality in MDS patients and is associated with poor prognosis. This study examined eight patients with monosomy 7 and MDS. Five MDS patients with monosomy 7 progressed to acute leukemia: three cases transformed into acute myelogenous leukemia (AML) in a mean time of only 4.6 months and two cases into acute lymphoblastic leukemia (ALL) in a mean time of 9 months. To our knowledge, this is the first report showing progression of monosomy 7 associated with MDS to ALL in the childhood period.

Abstract
Severe type I plasminogen (PLG) deficiency has been causally linked to a rare chronic inflammatory disease of the mucous membranes that may be life threatening. Here we report clinical manifestations, PLG plasma levels, and molecular genetic status of the PLG gene of 50 patients. The most common clinical manifestations among these patients were ligneous conjunctivitis (80%) and ligneous gingivitis (34%), followed by less common manifestations such as ligneous vaginitis (8%), and involvement of the respiratory tract (16%), the ears (14%), or the gastrointestinal tract (2%). Four patients showed congenital occlusive hydrocephalus, 2 with Dandy-Walker malformation of cerebellum. Venous thrombosis was not observed. In all patients, plasma PLG levels were markedly reduced. In 38 patients, distinct mutations in the PLG gene were identified. The most common genetic alteration was a K19E mutation found in 34% of patients. Transient in vitro expression of PLG mutants R134K, delK212, R216H, P285T, P285A, T319_N320insN, and R776H in transfected COS-7 cells revealed significantly impaired secretion and increased degradation of PLG. These results demonstrate impaired secretion of mutant PLG proteins as a common molecular pathomechanism in type I PLG deficiency.

Abstract
The cytochrome P4501A1 (CYP1A1) is involved in the metabolism of environmental carcinogens and estrogen. We hypothesized that CYP1A1 genetic polymorphism may be a susceptibility factor for endometrial hyperplasia (EH) and endometrial carcinoma (ECa). We therefore evaluated this hypothesis in patients with EH and ECa and control subjects using allele-specific polymerase chain reaction-based method in a Turkish population. The patients with CYP1A1 Ile/Val genotype had a fivefold higher risk of having EH than those with Ile/Ile. In contrast, a higher frequency of any Val genotype (Ile/Val and Val/Val) was found in patients with EH, indicating that persons carrying any Val allele are at increased risk for developing EH. In the ECa group, patients were also more likely to have CYP1A1 Ile/Val allele, with an adjusted odds ratio of 3.0. Moreover, there was a statistically significant increase in relative risk association with any Val genotype between patients and controls, suggesting that individuals carrying any Val genotype are at increased risk for developing ECa. We concluded that variant alleles of the CYP1A1 gene might be associated with EH and ECa susceptibility. Further studies with a large sample size should be considered to address issues of interactions between CYP1A1 and other risk factors.

Among the structural abnormalities affecting the human Y chromosome, dicentric chromosomes are the most common. A wide spectrum of phenotypes of patients with a dicentric Y chromosome exists, ranging from almost males through mixed gonadal dysgenesis to females with Turner syndrome. Here, we describe an infant with mixed gonadal dysgenesis and mosaic karyotype 45,X/46,X,idic(Y)(qter-->p11.32:p11.32-->qter)/47,X,+2idic(Y) (qter-->p11.32:p11.32-->qter)/47,XYY. This was demonstrated by fluorescence in situ hybridization (FISH) analysis with whole Y chromosome painting (WCP-Y) probe. Molecular studies were performed on genomic DNA extracted from peripheral blood lymphocytes. To examine the sex determined region (SRY), azoospermia factor (AZF) region and deletion in azoospermia gene (DAZ), polymerase chain reaction (PCR) analyses were done with sequence-tagged site (STS) primers of 20 loci along the Y chromosome (SRY, DYS271, DYS148, DYS273, KALY, DYS212, SMCY, DYS215, DYS218, DYS219, DYS221, DYS223, DYS224, DYF51S1, DYS236, DAZ, DYS240), and all tested loci were found positive. Because of the possibility of a mutation in the SRY gene, we analyzed the PCR fragment by DNA sequencing and did not observe any mutation or nucleotide alteration. We present detailed molecular-cytogenetic characterization of a patient with idic(Y)(p11.32), and results are discussed with the previously described patients. As far as we know, this is the fifth report of a 46,X, idic(Y)(p11.32) karyotype and the first presentation with mixed gonadal dysgenesis and isodicentric Y. Since the correlation between phenotype and karyotype is not yet well defined, the clinical reports will be helpful in defining the phenotypic range of this chromosomal abnormality.

Abstract
OBJECTIVE The purpose of this study was to evaluate the role of CYP1A1*3 gene polymorphism in the development of cervical cancer by comparing patients having cervical intraepithelial neoplasia (CIN) or invasive cervical cancer with control subjects. METHODS CYP1A1*3 polymorphism was analyzed using an allele-specific PCR-based method. RESULTS In the group of patients with CIN, the frequency of the Ile/Val and of any Val alleles was significantly higher than in the healthy control subjects (OR: 4.51; 95%CI = 2.42-8.43, and OR: 3.71; 95%CI = 2.03-6.78). In the CIN1 group, patients with Ile/Val and any Val genotypes were found to be significantly higher (OR: 10.53; 95%CI = 3.78-29.33 and OR: 8.38; 95%CI = 3.04-23.08). In the CIN2 group, patients with Ile/Val and any Val revealed a 4.06- and 3.23-fold higher risk than those with Ile/Ile (95%CI = 1.54-10.74 and 1.24-8.45). However, the variance in the group of patients with CIN3 did not reach statistical significance. Patients with cervical cancer were analyzed with respect to the histological diagnoses. In the adenocancer group, the estimated ORs with respect to the control subjects were 11.29 for Ile/Val (95%CI = 3.35-38.07) and 8.98 for any Val groups (95%CI = 2.69-30.01), with a statistical significance. Among the squamous cell cancer patients, Ile/Val and any Val were significantly higher than in controls (OR: 5.76; 95%CI = 3.13-10.59 and OR: 5.20; 95%CI = 2.91-9.28). Although Val/Val genotype did not reach a significant value, it was near significance with an OR of 3.03 (95%CI = 0.95-9.68). CONCLUSION These results suggest that CYP1A1*3 gene polymorphism is linked to a propensity for cervical carcinogenesis and further series are needed to detect the exact role of this unique variation.

Abstract
The cytochrome P4501A1 (CYP1A1) is involved in the metabolism of environmental carcinogens and estrogen. We hypothesized that CYP1A1 genetic polymorphism may be a susceptibility factor for endometrial hyperplasia (EH) and endometrial carcinoma (ECa). We therefore evaluated this hypothesis in patients with EH and ECa and control subjects using allele-specific polymerase chain reaction–based method in a Turkish population. The patients with CYP1A1 Ile/Val genotype had a fivefold higher risk of having EH than those with Ile/Ile. In contrast, a higher frequency of any Val genotype (Ile/Val and Val/Val) was found in patients with EH, indicating that persons carrying any Val allele are at increased risk for developing EH. In the ECa group, patients were also more likely to have CYP1A1 Ile/Val allele, with an adjusted odds ratio of 3.0. Moreover, there was a statistically significant increase in relative risk association with any Val genotype between patients and controls, suggesting that individuals carrying any Val genotype are at increased risk for developing ECa. We concluded that variant alleles of the CYP1A1 gene might be associated with EH and ECa susceptibility. Further studies with a large sample size should be considered to address issues of interactions between CYP1A1 and other risk factors.

Abstract
Chromosomal imbalance affecting the long arm of chromosome 4 has been reported in a variety of distinct clinical conditions. Common clinical findings have been described for 4q deletions distal to 4q33 and termed as 4q terminal deletion syndrome. We report two children with de novo chromosomal abnormality consisting of a terminal deletion (q33qter) of chromosome 4 in mosaic form. The phenotypes of these two patients are very similar to that described in the literature, but milder because of the mosaic nature of cytogenetic abnormality.

Abstract
Despite high incidence rates of prostate cancer, the genetic basis of this disease is not well understood. An association between risk and the CYP1A1 polymorphism has been noticed for several cancers, and the GSTM1 gene is one of the most extensively studied genes concerning polymorphism and cancer risk. These gene polymorphisms may play a role in the development prostate cancer (PCa) in Turkish populations; we therefore assessed the association of CYP1A1 and GSTM1 polymorphisms in patients with PCa in our population through a case-control study. One hundred patients with PCa and 107 control subjects were analyzed with an allele-specific polymerase chain reaction method. No statistical differences in the distribution of the CYP1A1 Ile/Val genotype among PCa individuals were observed (OR = 1.076, 95% CI = 0.605-1.913). The patients with CYP1A1 Val/Val revealed a 2.8-fold higher risk of having prostate cancer than those with the wild-type Ile/Ile (OR = 2.846, 95% CI = 1.004-8.064). In other words, the presence of the Val/Val genotype significantly increased the risk of prostate cancer. The GSTM1 null genotype was found in 13.1% of the control subjects; no statistical differences were noted in the frequency of the null genotype in patients with PCa (OR = 1.558, 95% CI = 0.735-3.305). We also analyzed the effects of the CYP1A1 and GSTM1 genotypes in combination; however, no significant difference between cases and controls was observed in our study population. These data suggest that the CYP1A1 gene polymorphism may be associated with PCa susceptibility in Turkish men and that further studies will be needed to clarify the role of such variations in determining susceptibility to PCa.

Abstract
The myelodysplastic syndromes (MDS) comprise a group of clonal hemopoietic stem cell disorders characterized by ineffective hematopoiesis with an increased propensity to myeloid leukemic (AML) transformation. The underlying molecular basis for MDS and its leukemic evolution is unclear. Except for patients with 17p syndrome, loss of function of the p53 tumor suppressor gene accounts for <10% of MDS and AML cases. Recently, mutations of the checkpoint gene, CHK2, the human homologue of the yeast CDS1 and RAD53 genes, have been reported in patients with Li-Fraumeni syndrome who also have normal p53. As p53 mutations are rare in MDS and AML, we investigated the status of the CHK2 gene by reverse transcriptase-polymerase chain reaction (RT-PCR) in patients with MDS (n=10) and patients in whom MDS had transformed into AML (n=3). In the MDS group, we found one patient with a conserved mutation (Lys-->Arg) in the forked head-associated (FHA) domain of the CHK2 coding sequence. We also found a deletion in the CHK2 transcript in one patient from the MDS-->AML group, resulting in a truncated protein lacking the kinase domain. We conclude that alterations of CHK2 and possible involvement in the pathogenesis of MDS may be a rare event.

Abstract
OBJECTIVE Gene-environment interactions have been the focus of a number of recent studies of the occurrence of human cancers, and an association between the risk and the CYP1A1*3 polymorphism has been noticed for several cancers. Previous studies suggest that estrogens are involved in the etiology of ovarian cancer. The cytochrome P450 1A1 (CYP1A1) gene polymorphism may play role in the development of epithelial ovarian neoplasm by detoxification of polycyclic hydrocarbons and other compounds and the concentration of estrogens and their metabolites. Therefore, we assessed the association of CYP1A1 gene polymorphism in patients with epithelial ovarian neoplasm in the Turkish populations through a case-control study. METHODS Using an allele-specific polymerase chain reaction (PCR)-based method, CYP1A1*3 polymorphism, in exon 7 of the gene, was analyzed in 117 epithelial ovarian neoplasm patients and 202 control subjects. RESULTS The CYP1A1 Ile/Val genotype significantly increased the risk for patients with epithelial ovarian neoplasm (OR 5.7, 95% CI 3.34-9.76). Furthermore, there were statistical differences in the distribution of CYP1A1 Val/Val genotype among all patients (OR 5.85, 95% CI 2.40-14.25). In other words, the presence of the Val allele significantly increased the risk of epithelial ovarian neoplasm. Among benign tumors, the frequency of Ile/Val and Val/Val genotypes was found to be statistically significant with an ORs of 6.01 and 4.38 (95% CI 2.61-13.84 and 1.04-18.38, respectively). In the benign serous ovarian tumors, patients with Ile/Val and Val/Val revealed a 7.2- and 10.5-fold higher risk of having ovarian carcinoma (95% CI 2.22-23.40 and 2.16-51.19), respectively. In the benign mucinous ovarian carcinoma patients, the frequency of Ile/Val was found to be statistically significant with an OR of 5.15 (95% CI 1.75-15.16). However, no patient with Val/Val genotype was observed in this group and no statistical distribution was performed. Among borderline tumors, CYP1A1 Ile/Val genotype significantly increased the risk for patients (OR 5.15, 95% CI 1.75-15.16). However, only one patient was observed with the Val/Val allele and the frequency of this genotype was not found to be statistically different with an OR of 2.50 (95% CI 0.27-22.64). Among ovarian cancer patients, there were statistically differences in the distribution of CYP1A1 Ile/Val and Val/Val genotypes (OR 5.73, 95% CI 3.04-10.76; and OR 7.42, 95% CI 2.80-19.66), suggesting that patients carrying these genotypes were at increased risk for ovarian carcinoma. In serous carcinoma, patients with CYP1A1 Ile/Val and Val/Val revealed a 6.5- and 10-fold higher risk of having ovarian cancer (OR 7.09, 95% CI 3.30-15.22; and OR 8.77, 95% CI 2.83-27.14). In mucinous carcinoma, patients with CYP1A1 Ile/Val and Val/Val also revealed a 5.4 and 10.5 times higher risk of having ovarian cancer. There were no statistical significance in the distribution of Val allele among endometroid-type cancer patients. CONCLUSIONS Our data, although based on a small number of subjects, suggest that variant alleles of CYP1A1 gene in ovarian epithelial cells, directly or through other components, may contribute to initiation of ovarian carcinogenesis.

Abstract
Cosmetic outcome of the columellar incision closure in external rhinoplasty patients has been a subject of discussion. This study was conducted to assess whether tissue adhesives provide an alternative option for sutureless closure of columellar skin incisions for cases utilizing open technique rhinoplastic surgery. One hundred and one patients undergoing external rhinoplasty were randomized to either topical application of butylcyanoacrylate or polypropylene sutures for columellar skin closure. The majority of tension on the wound edges was taken up using 5-0 chromic catgut. Cosmetic outcomes were evaluated by two otolaryngologists independently using visual analogue and Hollander wound evaluation scales in a blinded manner. There was no statistically significant difference in cosmesis between the surgeons' evaluation scores for either type or repair of the columellar incision. Since the tissue adhesive forms its own protective barrier, post-operative care is simplified. Closure with adhesives eliminates the need for post-operative suture removal requiring an extra visit that should lead to more efficient use of physician and patient time. Butylcyanoacrylate performs cosmetically as well as standard suture closure of columellar skin incision used for external rhinoplasty.

Abstract
At 17th week of pregnancy, a 28-year-old woman was diagnosed as having herpes simplex encephalitis and treated with intravenous acyclovir. Follow-up by the serial ultrasound examinations, intrauterine growth retardation (IUGR) was found. During the course of disease, cordocentesis was performed to evaluate the risk of the disease and the infant's chromosomal constitution. No herpes simplex virus infection on cord blood sample was observed; however, chromosomal analysis revealed: 46,XX/47,XX,+2/47,XX,+11/47,XX,+19/48,XX,+11. After termination of pregnancy, the fetus was found as having ventricular septum defect. The presence of the triploid cell lines mocaicism involving chromosome 2 and 19 were confirmed by the analysis of fetal skin tissues. No attributable finding to herpes simplex virus infection and acyclovir treatment was found, and the presence of the triploid cell lines mocaicism were appeared to be purely coincidental.

Abstract
Tetrasomy 8 is a relatively rare chromosomal abnormality in hematological disorders, and is mostly associated with myeloid malignancies and poor prognosis. In a number of cases, tetrasomy 8 has been reported as an accompanying anomaly with other chromosomal changes. In this report, we describe a 14-year-old girl with acute megakaryoblastic leukemia associated with tetrasomy 8 (primary) and trisomy 6, 19 and 20. She died 6 months after diagnosis, suggesting a relatively poor prognosis for AML with tetrasomy 8. To the best of our knowledge, this is the first report of a tetrasomy 8 abnormality associated with subtype FAB M7. Interestingly, this abnormality has not been previously reported in childhood AML patients.

Abstract
The glutathione S-transferase M1 (GSTM1) gene is polymorphic in humans, and the deficiency in enzyme activity of GSTM1 is caused by the inherited homozygous absence of the GSTM1 gene, or the "null" genotype (GSTM1, 0/0). The increased risk of bladder cancer has been shown to correspond with this gene defect. No reports, however, have been found in the literature regarding GSTM1 gene deficiency with superficial and invasive bladder cancer. In this study, we examined the association of the GSTM1-null genotype with superficial and invasive bladder cancer. Using a polymerase chain reaction (PCR)-based method, we examined the frequency of the GSTM1 gene defect in Turkish patients with superficial bladder cancer (N = 61), invasive bladder cancer (N = 42), and control subjects (N = 202) who had no history of cancer. The GSTM1 null genotype was observed in 34.7% of the control subjects and in 54.3% of total bladder cancer patients (OR: 2.246; 95% CI: 1.384-3.645, P: 0.00094). In other words, the presence of the GSTM1-null genotype significantly increased the risk of bladder cancer development. Among invasive bladder cancers, the frequency of the GSTM1-null genotype was 64.3% (OR: 0.294, 95% CI: 0.147-0.590, P: 0.0003). This was also significantly higher than control subjects, indicating that patients carrying this genotype were at increased risk for developing invasive bladder cancer. This relationship was not statistically significant in the superficial bladder cancer group (OR: 0.585, 95% CI: 0.327-1.045, P: 0.06). Our results indicate that GSTM1 gene polymorphism should be considered as an important risk modifier in the development of bladder cancer and might be used as a predictive marker for invasive bladder cancer.

Abstract
A noninvasive antibody test was used to identify male fragile X patients in special education schools, on the basis of the lack of FMRP in hair roots. We studied 300 males with mental retardation of unknown cause attending special schools. Patients were divided into two groups, based on the scores according to a fragile X check list (Group 1 </= 9 points and Group 2 >/= 10 points). Group 2 consists of 51 males and only 5 males in this group showed no FMRP expression in hair roots within the abnormal range (91%). Fragile X diagnosis in these cases was confirmed by DNA analysis. None of the males scoring more than 10 on the check list was diagnosed positive for the fragile X syndrome using DNA analysis. With our antibody test on hair roots we did not detect a fragile X patient in Group 1. The FMRP antibody test on hair roots is suitable in a screening program for the fragile X syndrome among mentally retarded males attending special education schools.
