Abstract
Primary failure of eruption (PFE) is a rare non-syndromic condition involving total or partial non-eruption of posterior teeth in the absence of mechanical obstruction. This paper presents the case of a healthy girl referred at age 4 for asymmetry of the upper arch. Clinical examination confirmed a slight shift of the upper midline to the left, with no erupted teeth distal to the upper left canine and a left posterior open bite. Panoramic X-rays showed delayed intraosseous development of the lateral left upper teeth compared to the right side. Clinic and radiographic follow-up during the next 9 years showed that 26 had not erupted by almost 13 years of age, 27 had delayed development and an unusual shape, and there was an agenesis in 24 and 25. Genetic analysis using the PTH1R single-gene sequencing method did not detect any known disease-causing or rare pathogenic variants that could explain the patient's phenotype. Even when detected early, PFE raises difficult problems with regard to diagnosis and ortho-surgical treatment planning due to the impossibility of accurately predicting its evolution. Tooth agenesis on the same arch worsens the prognosis and adds challenges to planning the treatment. Close long-term follow-up and timely adjustment of the treatment plan in accordance with the evolution of the case are needed.

Abstract
A hydatidiform mole (HM) or molar pregnancy is the most common benign form of gestational trophoblastic disease characterized by a proliferation of the trophoblastic epithelium and villous edema. Hydatidiform moles are classified into two forms: complete and partial hydatidiform moles. These two types of HM present morphologic, histopathologic and cytogenetic differences. Usually, hydatidiform moles are a unique event, but some women present a recurrent form of complete hydatidiform moles that can be sporadic or familial. The appearance of hydatidiform moles is correlated with some genetic events (like uniparental disomy, triploidy or diandry) specific to meiosis and is the first step of embryo development. The familial forms are determined by variants in some genes, with NLRP7 and KHDC3L being the most important ones. The identification of different types of hydatidiform moles and their subsequent mechanisms is important to calculate the recurrence risk and estimate the method of progression to a malign form. This review synthesizes the heterogeneous mechanisms and their implications in genetic counseling.

Abstract
Cancer predisposition syndromes are entities determined especially by germinal pathogenic variants, with most of them autosomal dominantly inherited. The risk of a form of cancer is variable throughout life and affects various organs, including the thyroid. Knowing the heterogeneous clinical picture and the existing genotype-phenotype correlations in some forms of thyroid cancer associated with these syndromes is important for adequate and early management of patients and families. This review synthesizes the current knowledge on genes and proteins involved in cancer predisposition syndromes with thyroid cancer and the phenomena of heterogeneity (locus, allelic, mutational, and clinical).

Abstract
Atherogenic dyslipidemia plays a critical role in the development of metabolic syndrome (MetS), being one of its major components, along with central obesity, insulin resistance, and hypertension. In recent years, the development of molecular genetics techniques and extended analysis at the genome or exome level has led to important progress in the identification of genetic factors (heritability) involved in lipid metabolism disorders associated with MetS. In this review, we have proposed to present the current knowledge related to the genetic etiology of atherogenic dyslipidemia, but also possible challenges for future studies. Data from the literature provided by candidate gene-based association studies or extended studies, such as genome-wide association studies (GWAS) and whole exome sequencing (WES,) have revealed that atherogenic dyslipidemia presents a marked genetic heterogeneity (monogenic or complex, multifactorial). Despite sustained efforts, many of the genetic factors still remain unidentified (missing heritability). In the future, the identification of new genes and the molecular mechanisms by which they intervene in lipid disorders will allow the development of innovative therapies that act on specific targets. In addition, the use of polygenic risk scores (PRS) or specific biomarkers to identify individuals at increased risk of atherogenic dyslipidemia and/or other components of MetS will allow effective preventive measures and personalized therapy.

Abstract
Factor V (FV) Leiden and prothrombin G20210A are the most common hereditary thrombophilias. While their role in venous thromboembolism is well known, there are still uncertainties regarding their relationship with arterial thrombotic events, especially coronary ones. Our research, based on an in-depth analysis of the available literature, provides up-to-date information on the relationship between FV Leiden and prothrombin G20210A and acute myocardial infarction. FV Leiden and prothrombin G20210A screening should be implemented only in select cases, such as acute coronary syndrome in young individuals and/or in the absence of traditional cardiovascular risk factors and/or in the absence of significant coronary artery stenosis at angiography. Their identification should be followed by the implementation of optimal control of modifiable traditional cardiovascular risk factors to reduce the risk of recurrent events and genotyping and genetic counseling of all family members of affected cases for proper prophylaxis. An extended dual antiplatelet therapy (DAPT) may be considered, given the lower risk of bleeding under DAPT conferred by FV Leiden.

Abstract
Osteogenesis imperfecta (OI) is a genetically heterogeneous monogenic disease characterized by decreased bone mass, bone fragility, and recurrent fractures. The phenotypic spectrum varies considerably ranging from prenatal fractures with lethal outcomes to mild forms with few fractures and normal stature. The basic mechanism is a collagen-related defect, not only in synthesis but also in folding, processing, bone mineralization, or osteoblast function. In recent years, great progress has been made in identifying new genes and molecular mechanisms underlying OI. In this context, the classification of OI has been revised several times and different types are used. The Sillence classification, based on clinical and radiological characteristics, is currently used as a grading of clinical severity. Based on the metabolic pathway, the functional classification allows identifying regulatory elements and targeting specific therapeutic approaches. Genetic classification has the advantage of identifying the inheritance pattern, an essential element for genetic counseling and prophylaxis. Although genotype-phenotype correlations may sometimes be challenging, genetic diagnosis allows a personalized management strategy, accurate family planning, and pregnancy management decisions including options for mode of delivery, or early antenatal OI treatment. Future research on molecular pathways and pathogenic variants involved could lead to the development of genotype-based therapeutic approaches. This narrative review summarizes our current understanding of genes, molecular mechanisms involved in OI, classifications, and their utility in prophylaxis.

Abstract
Melanoma is a common and aggressive tumor originating from melanocytes. The increasing incidence of cutaneous melanoma in recent last decades highlights the need for predictive biomarkers studies. Melanoma development is a complex process, involving the interplay of genetic, epigenetic, and environmental factors. Genetic aberrations include BRAF, NRAS, NF1, MAP2K1/MAP2K2, KIT, GNAQ, GNA11, CDKN2A, TERT mutations, and translocations of kinases. Epigenetic alterations involve microRNAs, non-coding RNAs, histones modifications, and abnormal DNA methylations. Genetic aberrations and epigenetic marks are important as biomarkers for the diagnosis, prognosis, and prediction of disease recurrence, and for therapeutic targets. This review summarizes our current knowledge of the genomic and epigenetic changes in melanoma and discusses the latest scientific information.

Abstract
The corpus callosum is the largest white matter structure connecting the two cerebral hemispheres. Agenesis of the corpus callosum (ACC), complete or partial, is one of the most common cerebral malformations in humans with a reported incidence ranging between 1.8 per 10,000 livebirths to 230–600 per 10,000 in children and its presence is associated with neurodevelopmental disability. ACC may occur as an isolated anomaly or as a component of a complex disorder, caused by genetic changes, teratogenic exposures or vascular factors. Genetic causes are complex and include complete or partial chromosomal anomalies, autosomal dominant, autosomal recessive or X-linked monogenic disorders, which can be either de novo or inherited. The extreme genetic heterogeneity, illustrated by the large number of syndromes associated with ACC, highlight the underlying complexity of corpus callosum development. ACC is associated with a wide spectrum of clinical manifestations ranging from asymptomatic to neonatal death. The most common features are epilepsy, motor impairment and intellectual disability. The understanding of the genetic heterogeneity of ACC may be essential for the diagnosis, developing early intervention strategies, and informed family planning. This review summarizes our current understanding of the genetic heterogeneity in ACC and discusses latest discoveries.

Abstract
Bardet – Biedl syndrome is a rare autosomal recessive multisystem non-motile ciliopathy. It has heterogeneous clinical manifestations. It is caused by mutations in 26 genes encoding BBSome proteins, chaperonines, and IFT complex. The main clinical features are: retinal cone-rod dystrophy, central obesity, postaxial polydactyly, cognitive impairment, hypogonadism and genitourinary anomalies, and kidney disease. The onset of clinical manifestations is variable which makes the diagnosis difficult in some patients. Because of the multiple system involvement, a multidisciplinary approach is necessary. The purpose of this review is to provide monitoring and management directions for a better approach to these patients.

Abstract
Modern antineoplastic therapy improves survival and quality of life in cancer patients, but its indisputable benefits are accompanied by multiple and major side effects, such as cardiovascular ones. Endothelial dysfunction, arterial spasm, intravascular thrombosis, and accelerated atherosclerosis affect the coronary arteries, leading to acute and chronic coronary syndromes that negatively interfere with the oncologic treatment. The cardiac toxicity of antineoplastic agents may be mitigated by using adequate prophylactic measures. In the absence of dedicated guidelines, our work provides the most comprehensive, systematized, structured, and up-to-date analyses of the available literature focusing on measures aiming to protect the coronary arteries from the toxicity of cancer therapy. Our work facilitates the implementation of these measures in daily practice. The ultimate goal is to offer clinicians the necessary data for a personalized therapeutic approach for cancer patients receiving evidence-based oncology treatments with potential cardiovascular toxicity.

Abstract
In the modern era, coronary artery disease (CAD) has become the most common form of heart disease and, due to the severity of its clinical manifestations and its acute complications, is a major cause of morbidity and mortality worldwide. The phenotypic variability of CAD is correlated with the complex etiology, multifactorial (caused by the interaction of genetic and environmental factors) but also monogenic. The purpose of this review is to present the genetic factors involved in the etiology of CAD and their relationship to the pathogenic mechanisms of the disease. Method: we analyzed data from the literature, starting with candidate gene-based association studies, then continuing with extensive association studies such as Genome-Wide Association Studies (GWAS) and Whole Exome Sequencing (WES). The results of these studies revealed that the number of genetic factors involved in CAD etiology is impressive. The identification of new genetic factors through GWASs offers new perspectives on understanding the complex pathophysiological mechanisms that determine CAD. In conclusion, deciphering the genetic architecture of CAD by extended genomic analysis (GWAS/WES) will establish new therapeutic targets and lead to the development of new treatments. The identification of individuals at high risk for CAD using polygenic risk scores (PRS) will allow early prophylactic measures and personalized therapy to improve their prognosis.

Abstract
Background and Objectives: Non-invasive prenatal testing (NIPT) has been confirmed as the most accurate screening test for trisomies 21, 18, 13, sex chromosomes aneuploidies and several microdeletions. This study aimed to assess the accuracy of cell free DNA testing based on low-level whole-genome sequencing to screen for these chromosomal abnormalities and to evaluate the clinical performance of NIPT. Materials and Methods: 380 consecutive cases from a single genetic center, from Western Romania were included in this retrospective study. Cell-free nucleic acid extraction from maternal blood, DNA sequencing and analysis of sequenced regions were performed by BGI Hong Kong and Invitae USA to determine the risk of specific fetal chromosomal abnormalities. In high-risk cases the results were checked by direct analysis of fetal cells obtained by invasive methods: 6 chorionic villus sampling and 10 amniocenteses followed by combinations of QF-PCR, karyotyping and aCGH. Results: NIPT results indicated low risk in 95.76% of cases and high risk in 4.23%. Seven aneuploidies and one microdeletion were confirmed, the other results were found to be a false-positive. A gestational age of up to 22 weeks had no influence on fetal fraction. There were no significant differences in fetal fraction across the high and low risk groups. Conclusions: This is the first study in Romania to report the NIPT results. The confirmation rate was higher for autosomal aneuploidies compared to sex chromosome aneuploidies and microdeletions. All cases at risk for trisomy 21 were confirmed. Only one large fetal microdeletion detected by NIPT has been confirmed. False positive NIPT results, not confirmed by invasive methods, led to the decision to continue the pregnancy. The main limitation of the study is the small number of patients included. NIPT can be used as a screening method for all pregnancies, but in high-risk cases, an invasive confirmation test was performed.

Abstract
Bartter syndrome (BS) is a rare tubulopathy that causes polyuria, hypokalemia, hypochloremic metabolic alkalosis, and normotensive hyperreninemic hyperaldosteronism. It is characterized by locus, clinical, and allelic heterogeneity. Types 1-4 of BS are inherited according to an autosomal recessive pattern, while type 5, which is transient, is X linked. There are specific correlations between the clinical expression and the molecular defect, but since it is a rare disease, such studies are rare. Therapeutic interventions are different, being correlated with types of BS.

Abstract
Cystic fibrosis (CF) is a monogenic autosomal recessive disease caused by cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations. CF is characterized by a high phenotypic variability present even in patients with the same genotype. This is due to the intervention of modifier genes that interact with both the CFTR gene and environmental factors. The purpose of this review is to highlight the role of non-CFTR genetic factors (modifier genes) that contribute to phenotypic variability in CF. We analyzed literature data starting with candidate gene studies and continuing with extensive studies, such as genome-wide association studies (GWAS) and whole exome sequencing (WES). The results of both types of studies revealed that the number of modifier genes in CF patients is impressive. Their identification offers a new perspective on the pathophysiological mechanisms of the disease, paving the way for the understanding of other genetic disorders. In conclusion, in the future, genetic analysis, such as GWAS and WES, should be performed routinely. A challenge for future research is to integrate their results in the process of developing new classes of drugs, with a goal to improve the prognosis, increase life expectancy, and enhance quality of life among CF patients.

Abstract
We present a complex chromosomal anomaly identified using cytogenetic and molecular methods. The child was diagnosed during the neonatal period with a multiple congenital anomalies syndrome characterized by: flattened occipital region; slight turricephaly; tall and broad forehead; hypertelorism; deep-set eyes; down slanting and short palpebral fissures; epicanthic folds; prominent nose with wide root and bulbous tip; microstomia; micro-retrognathia, large, short philtrum with prominent reliefs; low set, prominent ears; and congenital heart disease. The GTG banding karyotype showed a 46,XY,der(10)(10pter→10q26.2::4q26→4qter) chromosomal formula and his mother presented an apparently balanced reciprocal translocation: 46,XX,t(4;10)(q26;q26.2). The chromosomal anomalies of the child were confirmed by MLPA, and supplementary investigation discovered a quadruplication of the 4q35.2 region. The mother has a triplication of the same chromosomal fragment (4q35.2). Using array-CGH, we described the anomalies completely. Thus, the boy has a 71,057 kb triplication of the 4q26-q35.2 region, a 562 kb microdeletion in the 10q26.3 region, and a 795 kb quadruplication of the 4q35.2 region, while the mother presents a 795 kb triplication of the 4q35.2 region. Analyzing these data, we consider that the boy's phenotype is influenced only by the 4q partial trisomy. We compare our case with similar cases, and we review the literature data.

Abstract
Circular RNA (circRNA) is a distinct class of non-coding RNA produced, in principle, using a back-splicing mechanism, conserved during evolution, with increased stability and a tissue-dependent expression. Circular RNA represents a functional molecule with roles in the regulation of transcription and splicing, microRNA sponge, and the modulation of protein–protein interaction. CircRNAs are involved in essential processes of life such as apoptosis, cell cycle, and proliferation. Due to the regulatory role (upregulation/downregulation) in pathogenic mechanisms of some diseases (including cancer), its potential roles as a biomarker or therapeutic target in these diseases were studied. This review focuses on the importance of circular RNA in cancer.

Abstract
Wolf–Hirschhorn syndrome (WHS), a rare disorder determined by distal 4p deletion, is characterized by a pre and postnatal growth retardation, hypotonia, intellectual disability, epilepsy, craniofacial dysmorphism, and congenital fusion anomalies. The clinical aspects are dependent on the deletion’ size. Our aim was to identify rare specific characteristics in a cohort of seven cases with 4p deletion and to assess the utility of Multiplex ligation-dependent probe amplification (MLPA) (cheap and sensitive test)—combined kits—as a diagnostic test and selection tool for cases that require other investigations (chromosomal microarray analysis—CMA, karyotype). For all cases we conducted a clinical examination with the main features identified: facial dysmorphism, intellectual disability, postnatal development delay, cardiac defects and hypotonia. In some cases, we observed seizures, structural brain abnormalities, immunodeficiencies, and renal anomalies. Prenatal growth retardation was detected in a relatively small number of cases, but postnatal growth failure was a constant feature. In all cases, the clinical diagnosis was confirmed by genetic analyses: karyotype and/or MLPA. In conclusion, renal and brain defects, as well as immunodeficiency are rare manifestations and should be looked for. Although CMA is the standard test, in our experience, MLPA is also a reliable screening method as the identified cases were either confirmed by MLPA or selected for further investigations.

Abstract
Gardner syndrome is a neoplasic disease that associates intestinal polyposis and colorectal adenocarcinoma with osteomas and soft tissue tumors determined by germline mutations in the APC gene. The early diagnosis and identification of high-risk individuals are important because patients have a 100% risk of colon cancer. We present the case of a family with Gardner syndrome. Cephalometric, panoramic X-rays and CBCT of the proband and her brother showed multiple osteomas affecting the skull bones, mandible and paranasal sinuses. The detailed family history showed an autosomal dominant transmission with the presence of the disease in the mother and maternal grandfather of the proband. Both had the typical signs of disease and died in the fourth decade of life. Based on these aspects the clinical diagnosis was Gardner syndrome. By gene sequencing, a novel pathogenic variant c.4609dup (p.Thr1537Asnfs*7) in heterozygous status was identified in the APC gene in both siblings. We reviewed literature data concerning the correlation between the localization of mutations in the APC gene and the extracolonic manifestations of familial adenomatous polyposis as well as their importance in early diagnosis and adequate oncological survey of patients and families based on abnormal genomic variants.

Abstract
BACKGROUND Polyploidy is a rare lethal cytogenetic anomaly in pregnancies, generally leading to pregnancy termination. This study aims to compare first and second trimester polyploidy in pregnancies and describe the underlying mechanisms. METHODS A retrospective study was conducted in three medical genetics laboratories, collecting cases from Eastern, Southern, and Western Romania. The period of interest was January 2008 to December 2018. Prenatal samples (chorionic villi and amniotic fluid) and miscarriage samples were tested by standard karyotyping, as well as QF-PCR or FISH as complementary or alternative techniques. RESULTS In first trimester pregnancies, we report cytogenetic results of chorionic villi samples from miscarriages: 25 triploid cases and 13 tetraploid cases. In second trimester samples obtained by amniocentesis, cytogenetic findings were positive for 17 triploid cases. Maternal age, age of the pregnancy, and fetal gender identified by ultrasound were recorded in all cases and, additionally, data on biochemical risk and ultrasonographic findings for second trimester pregnancies. CONCLUSIONS Cytogenetic investigations of spontaneous abortions provide valuable information on the cause of abortion. This information is crucial for genetic counseling and may also contribute to prenatal diagnosis in subsequent pregnancies.

Abstract
Background: We have investigated the main genetic causes for non-syndromic hearing impairment (NSHI) in the hearing impairment individuals from the North-Eastern Romania and proposed a cost-effective diagnosis protocol. Methods: MLPA followed by Sanger Sequencing were used for all 291 patients included in this study. Results: MLPA revealed abnormal results in 141 cases (48.45%): 57 (40.5%) were c.35delG homozygous, 26 (18.44%) were c.35delG heterozygous, 14 (9.93%) were compound heterozygous and 16 (11.35%) had other types of variants. The entire coding region of GJB2 was sequenced and out of 150 patients with normal results at MLPA, 29.33% had abnormal results: variants in heterozygous state: c.71G>A (28%), c.457G>A (20%), c.269T>C (12%), c.109G>A (12%), c.100A>T (12%), c.551G>C (8%). Out of 26 patients with c.35delG in heterozygous state, 38.46% were in fact compound heterozygous. Conclusions: We identified two variants: c.109G>A and c.100A>T that have not been reported in any study from Romania. MLPA is an inexpensive, rapid and reliable technique that could be a cost-effective diagnosis method, useful for patients with hearing impairment. It can be adaptable for the mutation spectrum in every population and followed by Sanger sequencing can provide a genetic diagnosis for patients with different degrees of hearing impairment.

Abstract
Primary immunodeficiencies are genetic diseases, mainly monogenic, that affect various components of the immune system and stages of the immune response. The category of combined immunodeficiencies with associated or syndromic features comprises over 70 clinical entities, characterized by heterogeneity of clinical presentation, mode of transmission, molecular, biological, mutational and immunological aspects. The mutational spectrum is wide, ranging from structural chromosomal abnormalities to gene mutations. The impact on the function of the proteins encoded by the genes involved is different; loss of function is most common, but situations with gain of function are also described. Most proteins have multiple functions and are components of several protein interaction networks. The pathophysiological mechanisms mainly involve: Missing enzymes, absent or non-functional proteins, abnormal DNA repair pathways, altered signal transduction, developmental arrest in immune differentiation, impairment of cell-to-cell and intracellular communications. Allelic heterogeneity, reduced penetrance and variable expressivity are genetic phenomena that cause diagnostic difficulties, especially since most are rare/very rare diseases, which is equivalent to delaying proper case management. Most primary immunodeficiencies are Mendelian diseases with X-linked or recessive inheritance, and molecular diagnosis allows the identification of family members at risk and the application of appropriate primary and secondary prevention measures in addition to the specific curative ones. In conclusion, recognizing heterogeneity and its sources is extremely important for current medical practice, but also for the theoretical value of improving biological and biomedical applications.

Abstract
CHARGE syndrome is an autosomal dominant condition caused by mutations in the chromodomain helicase DNA binding protein 7 (CHD7) gene. The present study reported on the case of a 16-month-old female with plurimalformative syndrome, whose etiology was identified by clinical whole-exome sequencing (WES) analysis. Clinical and follow-up assessments identified multiple craniofacial dysmorphisms, congenital defects and functional symptoms, including dysphagia and Marcus Gunn jaw winking synkinesis. Trio-WES analysis was performed for the patient and their parents and the presence of CHARGE syndrome was further indicated using single-molecule real-time sequencing. A de novo pathogenic variant, c.4379_4380del (p.Ile1460Argfs*15), was identified in exon 19 of the CHD7 gene, which resulted in a premature translational stop signal. Trio-WES analysis was used for further investigation, indicating that neither of the patient's parents had the mutation and confirming its de novo nature. To the best of our knowledge, the case of the present study was the first reported case of CHARGE syndrome in Romania with congenital defects including an aberrant right subclavian artery and a horseshoe kidney. CHARGE syndrome was diagnosed in the patient based on the pathogenic mutation in the CHD7 gene. To the best of our knowledge, the present case report is the first to suggest that the CHD7 gene variant is associated with CHARGE syndrome.

Abstract
BACKGROUND Osteogenesis imperfecta (OI) is a rare disease characterized by increased bone fragility and predisposition to fractures, bone deformities and other major signs such as dentinogenesis imperfecta, blue sclera and deafness. Over 90% of OI cases are caused by mutations in the COL1A1 and COL1A2 genes and the inheritance is autosomal dominant. METHODS We present a case of a couple requesting genetic counseling, because the man was diagnosed with OI on a clinical and radiological basis and the woman was pregnant. Whole exomes sequencing (WES) was performed in order to identify the mutation (s), followed by prenatal diagnosis. RESULTS WES identified a rare splicing mutation c.1155 + 1G > C in the COL1A1 gene recognized to be pathogenic and subsequently confirmed by next generation sequencing. The carrier state of the mutation was excluded for the fetus, so the pregnancy was further pursued and a healthy baby was born at term. CONCLUSIONS WES is a new and effective technique for detecting pathogenic variants in monogenic diseases and it is preferable to use such a technique in diseases with genetic heterogeneity especially when time does not allow another time-consuming diagnostic technique such classical Sanger sequencing. WES offers possibility to expand the global spectrum of OI pathogenic variants enabling the diagnosis of the disease.

Abstract
Holt-Oram syndrome (HOS) is a rare monogenic disorder characterized by upper limb abnormalities, congenital heart defects and/or conduction abnormalities. It is determined by mutations of TBX5 gene and is inherited in an autosomal dominant manner. Penetrance is complete, but variable expressivity is present, which gives sometimes diagnostic difficulties. Our case is a young adult with a personal history of preaxial polydactyly operated in infancy, multiple cardiac malformations (atrial septal defect, bicuspid aortic valve, left ventricular non-compaction) and radiologic findings consistent with HOS. Family history is negative for HOS. In conclusion, we present a case of HOS diagnosed in the adult period to highlight the diagnostic problems for the proband and the family and the importance of an early diagnostic.

Abstract
Introduction: Acute aortic dissection is the most common cause of death in patients with Marfan syndrome and untreated aortic root enlargement. Emergency surgery for replacement of the ascending aorta has the potential of life saving procedure, but is associated with high morbidity and mortality. Long-term outcomes after surgical repair of acute aortic dissection type A in patients with Marfan syndrome are limited. Material and methods: We made a retrospective study concerning emergency surgical intervention for acute aortic dissection type A, by Bentall procedure, performed in Emergency Institute for Cardiovascular Diseases „Prof dr. C. C. Iliescu” Bucharest between January 2005 and July 2014. We included 332 patients with type a acute aortic dissection divided into two groups: group A - 16 patients with Marfan syndrome and group B - 316 patients with other etiologies. We analyzed differences between these two groups regarding perioperative characteristics, surgical technique and short and long-term morbidity and mortality. Results: The patients from group A were significantly younger than those in group B (35.1±12.7 years vs. 56.8±7.1 years; p<0.001). Arterial hypertension was three times more common in group B as compared to group A (p<0.001). The incidence of postoperative morbidity, and intraoperative and 30-days mortality death rates were similar between groups, but overall mortality at 10 years was lower in group A (31.3%) vs. group B (44.9 %). Conclusions: Emergency surgical in Marfan syndrome, by Bentall procedure could improve perioperative morbidity and mortality of patients with acute aortic dissection, but need an early diagnosis, proper medical therapy and imagistic surveillance.

Abstract
Neurodegenerative diseases, such as Alzheimer's dementia, Huntington's chorea, Parkinson's disease or spinocerebellar ataxia, manifests into adulthood with an insidious onset, slowly of progressive symptoms. All of these diseases are characterized by presimptomatic stages that preceded with many years of clinical debut. In Parkinson's disease, more than half of the dopaminergic neurons of the black substance are lost before the advent of motor characteristic manifestations. In Huntington's chorea, the progressive neurodegenerative disease could be diagnose prenatal and presymptomatic by analyse of the number of CAG repeats in exon 1 of the huntingtin gene. A similar mechanism represented by expansion of trinucleotide repeats during hereditary transmission from parents to children was identified in fragile X syndrome, spinocerebellar ataxia, spinal muscular and bulbar atrophy, or myotonic dystrophy. Presymptomatic diagnosis in all these progressive diseases raise many ethical issues, due to the psychological impact that can cause the prediction of a disease for which there is currently no curative treatment. Therefore, a positive result can produce serious psychological trauma and major changes in the lifestyle of the individual, instead, a negative result can bring joy and tranquillity. But the problem arises if presymptomatic testing in these neurodegenerative diseases brings greater benefits compared to the possible psychological damage, which can add the risk of stigmatization or discrimination.

Abstract
AbstractTriploidy is a numerical chromosomal anomaly characterized by the presence of three sets of haploid chromosomes. The incidence is hard to evaluate, because usually it causes 1st trimester miscarriage. At 20 weeks of amenorrhea the incidence of triploidy is estimated at 1/250,000 cases. We present 4 cases of triploidy diagnosed during the decade 2003-2013 in the Prenatal Diagnosis Department of Maternity “Cuza-Vodă” Iasi, Romania, all registered in one year. The analysis of pathological cases identified in the last 11 years by prenatal diagnosis has shown that triploidies represented only 5.7% of numeric chromosomal anomalies, but in 2013 the four cases of triploidy represented 36% of numeric chromosomal anomalies. The karyotypes were recommended after discovering different congenital anomalies by ultrasound scan. In all cases, an intrauterine growth retardation (IUGR) was present but with no placental changes. Also, we discovered anomalies of limbs, congenital anomalies of heart and some dysmorphic features. This series demonstrates that triploidy may be discovered in the 2nd trimester of pregnancy and has a heterogeneous aspect at ultrasound scan, which can generate diagnostic difficulties. Therefore, the detection by ultrasound scan, at 18-22 weeks of pregnancy, of complex foetal morphological abnormalities should be an important reason for amniocentesis to search chromosomal anomalies

Abstract
AbstractThe coexistence of t(9;22) and inv(16) has been described in a very limited number of cases of CML, de novo or therapy-related AML. We report a patient with CML who presented both inversion of chromosome 16 and Philadelphia chromosome and evolved towards the blast phase under treatment with Imatinib. Laboratory diagnosis and monitoring was made by flow cytometry, conventional cytogenetics and molecular genetics techniques. The inv(16), detected by karyotyping in the Philadelphia chromosome positive clone at the moment of the blast transformation, was retrospectively assessed by means of real-time PCR, and was proved to have been present since diagnosis. The bone marrow biopsy performed in the blast phase of CML confirmed the presence of blasts belonging to the myeloid lineage, with indications of monocytic differentiation, frequently associated with inv(16). Moreover, the case also associated a F359V tyrosine kinase domain mutation, resulting in intermediate resistance to Imatinib and Nilotinib, which imposed therapy-switch to Dasatinib. In our case the evolution was progressive, followed by death due to lack of response to tyrosine kinase inhibitors, 18 months after diagnosis. The coexistence of t(9;22) and inv(16) in CML seems to be associated with an aggressive clinical evolution and resistance to tyrosine kinase inhibitor therapy. Due to the very small number of cases described in literature, therapeutic decisions are still difficult for patients displaying these abnormalities

Abstract
Roberts syndrome is a rare disease, with multiple limb and skeletal abnormalities (called "pseudothalidomide disease"). There are only around 150 cases described in literature. We present a case of Roberts syndrome, diagnosed in moment of delivery, after a pregnancy without prenatal follow-up. The stillborn baby was naturally delivered by a 17-year-old primiparous woman at 38 weeks of amenorrhea. The pregnancy was not followed due to socioeconomic and family situation, and no prenatal ultrasound was performed. The male baby has 2650 g and presented several morphological abnormalities and tight double umbilical abdominal loop. The macroscopic evaluation showed: dolichocephaly, hypoplastic inferior maxilla with micrognathia, antimongoloid palpebral slant, pterygium colli, abnormal and lower implanted ears, superior limbs phocomelia, syndactyly at lower left limb and tetradactyly in all limbs, bilateral cryptorchidism, pancreatic aplasia. Roberts syndrome is a rare genetic disease with recessive autosomal transmission generated by mutations in ESCO2 gene, located on chromosome 8. The disease should be easy to diagnose by antenatal ultrasound examination, but in our case, the lack of prenatal follow-up determined the diagnostic at term. We believe consider this case is an argument towards introducing ultrasound-screening compulsory to all pregnancies. To identify a possible genetic mutation, further investigations of the parents are in progress, but classically the disease has a recessive autosomal transmission.

Abstract
Inverted 8p duplication deletions are recurrent chromosomal rearrangements that most often arise through non-allelic homologous recombination (NAHR) during maternal meiosis between segmental duplications made up of the olfactory receptor (OR) gene clusters. The presence of a paracentric inversion polymorphism in 8p23.1, found in approximately 26% of European population, may trigger meiotic misalignment and NAHR between the OR gene repeats. We report clinical, cytogenetic, and molecular findings in a 4 year 8 month-old female with concomitant inverted duplication and terminal deletion of chromosome 8p. The girl, the first child of unrelated parents, was born at term, by normal delivery, after an uneventful pregnancy. Clinical examination revealed dysmorphic features, pectus excavatum, hypertonia, severe developmental delay. Brain ultrasound and MRI showed agenesis of the corpus callosum without other abnormalities. Conventional cytogenetic analysis identified additional material on chromosome 8 at band p21. SNP array analysis further characterized the abnormality as a duplication of about 31.3 Mb, from 8p23.1 to 8p11.1, and additionally revealed a terminal deletion of about 6.8 Mb, from 8p23.3 to 8p23.1. Genomic microarray also identified a region of disomy between deletion and duplication. Chromosome analysis of both parents revealed normal results. Based on clinical examination, conventional cytogenetics and SNP array, we established the diagnosis of inverted duplication deletion of 8p. SNP array analysis precisely defined the breakpoints of rearrangement and, by identifying a region of disomy between the duplication and deletion, indicated that NAHR between segmental duplications was the most likely mechanism for this type of abnormality.

Abstract
UNLABELLED Trisomy X (47,XXX) is a gonosomal aneuploidy characterized by the presence of an extra X chromosome in a female person. Usually the diagnosis is established made postnatally by chromosome analysis in patients with suggestive clinical signs. Clinical signs vary by age. In prepubertal patients have a growth retardation associated with uncharacteristic facial dysmorphism, mild mental retardation with behavioral disorders, plus clinical signs of ovarian dysgenesis, postpubertal. AIM We analyzed retrospectively the genotype - phenotype correlations for a selected group of 36 patients diagnosed with trisomy X (homogeneous or mosaic) by cytogenetic methods (X chromatin and karyotype). MATERIAL AND METHODS Analysis of the clinical data of 36 patients diagnosed with trisomy X and correlation with the results of X chromatin and karyotype. RESULTS Clinical signs detected in patients with homogeneous trisomy X 47,XXX (22.22%), mosaic 46,XX/47,XXX (16.66%) or 47,XXX/48,XXXX (5.55%) were prepubertal, growth retardation associated with dysmorphic facial (upslanted palpebral fissure, epichantus, thin lips) and postpubertal, signs of ovarian dysgenesis (secondary amenorrhea, early menopause). The phenotype of patients with different gonosomal mosaic corresponding to Turner syndrome, incorporating a cell line with trisomy X (55.55%) was variable, correlated with the type of chromosomal abnormalities detected. CONCLUSIONS The results of our study are similar to those obtained in other studies and emphasizes that phenotypic variability of patients with trisomy X feature makes it difficult to genotype - phenotype correlations.

Abstract
UNLABELLED Patau syndrome has an incidence of 1/10.000-20.000, the clinical diagnosis being suggested by the triad cleft lip and palate, microphthalmia/anophthalmia and postaxial polydactyly. Most frequent cytogenetic abnormality is free and homogeneous trisomy 13 (80.0%), rarely being detected trisomy mosaics or Robertsonian translocations. The objective of the study was to identify phenotypic features of trisomy 13. MATERIAL AND METHODS The retrospective study was conducted on a trial group of 14 cases diagnosed cytogenetically with trisomy 13 between January 2000 and December 2012 at lasi Medical Genetics Centre. RESULTS Of the 14 cases, 3 were evaluated pathologically (two aborted foetuses and one stillborn), 8 cases were detected in the neonatal period, and 3 in infancy. Clinical diagnosis was supported by the identification of a model of abnormal development, mainly characterized by: maxillary cleft (lip and palate--5 cases; lip--1 case), ocular abnormalities (microphthalmia/anophthalmia--7 cases; cyclopia--1 case), postaxial polydactyly (7 cases), scalp defects (6 cases), congenital heart anomalies (10 cases, 6 patients with atrial septal defect), complete holoprosencephaly (4 cases), ear abnormalities (11 cases), broad nasal root (10 cases). An important issue in confirming the phenotypic variability of Patau syndrome is that the classic clinical triad was identified only in one case. CONCLUSIONS Patau syndrome is a disease with variable expression and is characterized by a pattern of abnormal prenatal development characterized by facial dysmorphia, polydactyly and severe birth defects (heart, brain) that generate an increased in utero and perinatal mortality.

Abstract
UNLABELLED Prenatal diagnosis (PD) by FISH or cell culture is today an important tool for the prevention of chromosomal anomalies. A difficult issue is prenatal detection of gonosomal anomalies. Most gonosomal anomalies neither affect life expectancy nor cause psychomotor retardation, but sexualization disorders and the lack of reproductive potential are a constant finding. AIM This study aimed at identifying the medical problems the specialists and the parental couple are faced with at the time of the diagnosis of fetal gonosomal anomalies. MATERIAL AND METHODS This retrospective study (2004-2012) was conducted in the Prenatal Genetic Diagnosis Department of "CuzaVoda" Maternity by FISH technique in 1685 pregnancies. The AneuVysion probes were used for identifying and enumerating chromosomes 13, 18, 21, X, and Y via fluorescence in situ hybridization (FISH) in interphase nuclei obtained from amniotic fluid. RESULTS Fifteen fetuses were selected in which we were faced with difficulties interpreting the number of gonosomes: monosomy X (5 cases), pseudomosaicism XX/XY (3), trisomy XXY (3 cases), trisomy XYY (1 case), 45,X/46.XX mosaicism (1 case) and triploidy XXX (2 cases). Later, by repeating the analysis, 2 cases with pseudomosaicism XX/XY were excluded. A case highlighting the limitations of the FISH test was that of a fetus in which the FISH test revealed trisomy XXY, while postnatal karyotyping showed a six cell line mosaicism (marker and ring X chromosomes). CONCLUSIONS All parental couples received nondirective genetic counseling, respecting the individuals' dignity and rights of self-determination. Parents received information on the natural course of the disease, treatment options, and psychological support and were involved in their child's recovery.

Abstract
Hand, foot and mouth disease (HFMD) is a viral illness usually occurring during the summer months in children younger than 5 years of age. In the North-East area of Romania the incidence is usually low, each dermatologist reporting 1-2 cases or even less per year. The diagnosis is usually based on the characteristic clinical aspect: vesicles and papules on the hands and feet and superficial oral ulcers. HFMD is typically a benign and self-limiting disease that resolves in approximately 7 days; in Asia there have been few reported severe cases that developed neurological complications and even death, while in certain areas of China this disease is a more and more serious public health problem. In the summer of 2012 in North-East Romania numerous cases of disease have been reported, some with atypical clinical manifestations and most of them with mild or moderate forms of disease. The present article is a discussion on one of these cases. The diagnosis was made based on lesions location and clinical appearance. An outbreak of HFMD should be confirmed by virology tests.

Abstract
Ring chromosomes are rare entities, usually associated with phenotypic abnormalities in correlation with the loss of genetic material. There are various breakpoints and sometimes there is a dynamic mosaicism that is reflected in clinical features. Most of the ring chromosomes are de novo occurrences. Our study reflects the experience of three Romanian cytogenetic laboratories in the field of ring chromosomes. We present six cases with ring chromosomes involving chromosomes 5, 13, 18, and 21. All ring chromosomes were identified after birth in children with plurimalformative syndromes. The ring chromosome was present in mosaic form in three cases, and this feature reflects the ring's instability. In case of ring chromosome 5, we report a possible association with oculo-auriculo-vertebral spectrum.

Abstract
During the past ten years a particular molecular technology - array comparative genomic hybridization (aCGH)--has received a great deal of attention. Array CGH can detect simultaneously sub-microscopic copy number changes across the whole genome, thus overcoming the limitations of karyotyping or locus-specific techniques. Array CGH has become an important tool for clinical diagnostics and gene-identification studies and is having a great impact on the understanding of pathologies, the counselling of families and patient management. Different types of array CGH platforms at increasingly higher resolution have been developed, differing mainly in the type of the interrogating probes and in their coverage of the genome. Here, we review the array CGH methodology and its various applications in clinical diagnostics and research. Although it's an expensive technology and differentiating between pathogenic and benign copy number variations is a challenging task, array CGH is an efficient and robust method for assesing disease-causing genomic imbalances and will probably replace karyotype as the primary cytogenetic test.

Abstract
UNLABELLED Velo-Cardio-Facial Syndrome (VCFS) is characterized by congenital heart defects (CHD), palatal abnormalities, facial dysmorphism, neonatal hypocalcemia, immune deficit, speech and learning disabilities. SVCF is caused by microdeletion 22q11.2. Microdeletion is detected by fluorescence in situ hybridization (FISH). The highly variable phenotype makes diagnosis and selection for FISH more difficult. AIM To retrospectively analyze and compare the phenotype of children with a clinical diagnosis of VCFS with/without 22q11 deletion; to verify the validity of literature guidelines and to describe combinations of clinical features that should lead to molecular analysis. MATERIAL AND METHODS The present study was performed in 21 patients with a clinical diagnosis of VCFS. Methaphase chromosome spreads were prepared from phytohaemagglutinin stimulated lymphocyte culture by standard methods before FISH. The patients were divided into two groups according to FISH test: positive and negative. RESULTS The features commonly noticed in FISH positive patients were: palatal abnormalities/hypernasal speech, learning disabilities, facial dysmorphism, tapered fingers (6/6), CHD (5/6) and recurrent infections (2/6). In FISH negative patients the following were found: learning disabilities, CHD (12/15); facial dysmorphism (10/15), family history of CHD (7/15), short stature (6/15), hypocalcemia, tapered fingers (5/15), recurrent infections (3/15) and palatal cleft (2/15). In both groups, Tobias and McDonald-McGinn guidelines were positive. CONCLUSIONS VCFS has a highly variable phenotype. Our study suggests that 22q11.2 deletion analysis by FISH should be performed in patients who have at least 2 (newborn)/3 (child, adult) specific criteria: CHD, hypocalcemia, palatal abnormalities, facial dysmorphism, learning disabilities, digital anomalies, and immune deficit.

Abstract
UNLABELLED Reproductive Disorders (RD), manifested by the biological inability to conceive (primary sterility) or inability to carry a pregnancy to full-term (infertility), affect 10-15% of reproductive-aged couples. The genetic etiology of RD is represented, in the majority of cases, by the chromosomal abnormalities. AIM To retrospectively analyze the karyotype results in a selected group of couples with RD. MATERIAL AND METHOD The present study was performed in 266 couples with RD: 80 (30.07%) with primary sterility (ST), 149 (56.01%) with Recurrent Spontaneous Abortions (RSA) and 37 (13.90%) with Stillborn Children (SC). A GTG-banded karyotype was performed on both partners of each couple. RESULTS We identified a chromosomal abnormality in 43 individuals (16.16%): 20 cases (7.51%) with ST, 13 cases (4.88%) with RSA and 10 cases (3.75%) with SC. The affected partner was female in 23 cases (8.64%) and male in 20 cases (7.51%). A X chromosome (numerical or structural) abnormality was detected in 18 cases (6.76%), most frequent X chromosome monosomy mosaicism in female and trisomy XXY in male; a balanced structural chromosomal abnormality (BSC) was detected in 23 couples (8.64%); in other two males with ST, the karyotype result was 46,XX. CONCLUSIONS The results of our study are similar to other reported studies and underline the major etiologic role of chromosomal abnormalities in RD and the importance of chromosomal analysis for the etiologic diagnosis and genetic counseling of these patients.

Abstract
MATERIAL AND METHOD The study has been conducted on a period of ten years and it included 1570 children with congenital abnormalities (CA), of which 371 (24%) were cardiac abnormalities, 312 (20%) were skeletal abnormalities, 55 (3%) were Down Syndrome and 832 (53%) were other pathologies. RESULTS 48% of the 371 children that were diagnosed with cardiac CA were males, while 52% were females; 52% of the children were from the city, while 48% were from the country-side; 42% of the children have been born prematurely, while 58% of them have been born at normal term. 38% of the children had an APGAR score lower than 7 and 62% of them had an APGAR score higher than 7. Of the total number of births, 72% were caesarian births and 28% were natural births. The different types of Cardiac CA that have been encountered in the study were atrioventricular canal (56%), transposition of the great vessels (18%), common arterial trunk (10%), atrial septal defect (8%), ventricular septal defect (5%) and tetralogy of Fallot (3%). 66% of the total number of deaths were represented by those with cardiac pathology, 21% were caused by hydrocephalus, 7% were caused by diaphragmatic hernia, 4% had renal CA, while 2% were caused by other pathologies.

Abstract
UNLABELLED Congenital abnormalities (CA) are deviations from the normal embryonic development that appear antenatal and they are characterized by the alteration of the morphology and function of an organ, system of organs or even of the entire body. MATERIAL AND METHOD The study, on a period of eight years, included 1685 children with CA, from which 58% were males and 50% were from the country-side. RESULTS It has been observed that 36% of the CA cases were premature births and 64% were normal term births. Also, 21% of the children with CA weighed less than 2700 grams at birth and 79% weighed more than 2700 grams at birth. The birth's APGAR score has been less than 7 in 30% of the cases and higher than 7 in 70% of the cases. 72% of the cases were natural births and 28% were caesarian births. 88% of the CA cases were singular congenital abnormalities and 12% were multiple congenital abnormalities. 24% of the CA were cardiac abnormalities and 21% were skeletal abnormalities. 3% of the subjects of the study have died, of which 69% died from cardiac abnormalities, 22% from hydrocephalus abnormalities, 7% from diaphragmatic hernia and 2% from renal congenital abnormalities.

Abstract
We present a retrospective study aimed to identify the correlation between de Vries clinical score and the detection of chromosomal abnormalities in mentally retarded (MR) children. We have used the score to identify patients who should be tested by karyotyping and subsequently MLPA (multiplex ligation dependent probe amplification) for subtelomeric rearrangements. Our group is formed of 36 children with variable MR associated with other anomalies. 18 children had chromosomal defects, whereas 18 had normal karyotypes. In the first group, total scores varied between 3 and 7. Chromosomal anomalies identified were: numerical (4) and structural (14). Chromosomes involved were: 1, 4, 5, 7, 8, 9, 17, X. Deletions were the most common and correlate with a greater score (> or = 4). Common clinical features were: short stature, microcephaly, nasal, ear and hand anomalies. In the second group the most frequent clinical feature was hand anomaly (61.2%) and cases with a high score have to be further tested (e.g. using MLPA) in order to identify minor defects. In our opinion a high score indicates the karyotype and then a MLPA testing. In conclusion, we present a retrospective study that proves the use of de Vries diagnostic score in the identification of chromosomal abnormalities in MR children.

Abstract
The last years modified major our conceptions about nutrition. These revolutionary changes were produced by implementation of new techniques of functional genomics. The nutrigenomics and nutrigenomics provide powerful approaches to unravel the complex relationships between bioactive molecules, genetic polymorphisms and biological system and can give rise to personalized nutrition and dietary recommendations. In monogenic diseases (phenylketonuria, galactosemia, lactose intolerance etc.) diet influence phenotypic expression and nutrigenomics will improve the prevention or treatment by the early identification of specific mutations or haplotype combinations that modulate dietary response in affected subjects. In the multifactor diseases, like cardiovascular diseases (CVD), obesity, type II diabetes mellitus or cancer, the nutrigenomics approach has begun to reveal that some of them are susceptible to dietary intervention and may modulate the onset and progression of disorders.

Abstract
UNLABELLED Chromosomal disorders are severe and affect 0.9% of the newborns. In these conditions, prenatal diagnosis should be compulsory in every public medical system. MATERIAL AND METHOD Our study is a retrospective analysis of pregnant women investigated by amniocentesis and FISH technique. RESULTS We analyzed 233 samples collected between 2004 and 2007 at Iaşi "Cuza-Vodă" Obstetrics and Gynecology Hospital. The majority of cases were investigated between 16 and 24 weeks of pregnancy. Thirty-eight abnormal cases (16.30%) were identified: 17 cases with 21 trisomy, 16 cases with 18 trisomy, 3 cases with X monosomy, and 2 cases with 13 trisomy. The main reasons for amniocentesis were: advanced maternal age (12.5% abnormal cases) ultrasound abnormalities (26.15% abnormal cases), and biochemical abnormalities (7.14% abnormal cases). CONCLUSION Our data are in agreement with other studies, and support our results.

Abstract
UNLABELLED Down syndrome, determined by 21 trisomy, represents a major cause of infantile morbidity and mortality. AIM The analysis of dysmorphic features in Down syndrome, incidence of major congenital abnormalities, of some epidemiological parameters and cytogenetic specifics. MATERIAL AND METHOD Methods used were clinical, epidemiological and cytogenetical. We analysed 221 patients, from Iaşi county, with clinical supposition of Down syndrome, identified in the first year of life, between 1985 and 1999. RESULTS The majority of patients (67%) have more than 5 from 10 characteristics dysmorphic signs of Down syndrome in neonatal period. Visceral congenital abnormalities--82 cases (37.1%) were isolate (cardiac or digestive) or multiple. The presence of one visceral abnormality determined the death of patient in 30 cases (46.15% of death). Medium incidence of Down syndrome in Iaşi county was 1.306 per thousand (1/769 new-born), with median value 1.091per thousand and corrected value related to the maternal age 1.056 per thousand. Cytogenetic analysis was performed at 101 patients, in 95 cases (94.05%) clinical suspicion of Down syndrome was correct, patients presenting 21 trisomy (in the majority of cases a homogenous free trisomy). CONCLUSION The data obtained by us are concordant with the majority of literature studies, that a test the correctness of clinical trial and validate our results.

Abstract
The infertility is a important health problem, affecting about 10-15% of couples. The important role of genetic factors in pathogenesis of infertility is now increasingly recognized and our knowledge in this field are improved each day. For these reasons we review the most important genetic causes of infertility. In this paper we analyse the genetic implications in gonadal and postgonadal infertility. Gonadal infertility affects both sexes and are characterised by hypergonadotrophic hypogonadism. Gonadal infertility is produced by chromosomal or monogenic mutations. Chromosomal causes are represented by gonosomal aneuploidy and structural chromosomal abnormalities. The monogenic disorders are consequences of a recessive mutations of hormone, hormonal receptor or enzymes genes. Postgonadal infertility is present in men and is the result of some obstructive disorders.
