Abstract
Infertility affects ∼15% of couples globally and half of cases are related to genetic disorders. Despite growing data and unprecedented improvements in high-throughput sequencing technologies, accumulated fertility-related issues concerning genetic diagnosis and potential treatment are urgent to be solved. However, there is a lack of comprehensive platforms that characterise various infertility-related records to provide research applications for exploring infertility in-depth and genetic counselling of infertility couple. To solve this problem, we provide IDDB Xtra by further integrating phenotypic manifestations, genomic datasets, epigenetics, modulators in collaboration with numerous interactive tools into our previous infertility database, IDDB. IDDB Xtra houses manually-curated 2369 genes of human and nine model organisms, 273 chromosomal abnormalities, 884 phenotypes, 60 genomic datasets, 464 epigenetic records, 1144 modulators relevant to infertility diagnosis and treatment. Additionally, IDDB Xtra incorporated customized graphical applications for researchers and clinicians to decipher in-depth disease mechanisms from the perspectives of developmental atlas, mutation effects, and clinical manifestations. Users can browse genes across developmental stages of human and mouse, filter candidate genes, mine potential variants and retrieve infertility biomedical network in an intuitive web interface. In summary, IDDB Xtra not only captures valuable research and data, but also provides useful applications to facilitate the genetic counselling and drug discovery of infertility. IDDB Xtra is freely available at https://mdl.shsmu.edu.cn/IDDB/and http://www.allostery.net/IDDB.

Abstract
BACKGROUND Genome Mapping Technologies (optical and electronic) use ultra-high molecular weight DNA to detect structural variation and have application in constitutional genetic disorders, hematological neoplasms, and solid tumors. Genome mapping can detect balanced and unbalanced structural variation, copy number changes, and haplotypes. The technique is analogous to chromosomal microarray analysis, although genome mapping has the added benefit of being able to detect and ascertain the nature of more abnormalities in a single assay than array, karyotyping, or FISH alone. KEY MESSAGES This paper describes a specific nomenclature for genome mapping that can be used by diagnostic and research centers to report their findings accurately. An international nomenclature is essential for patient results to be understood by different healthcare providers as well as for clear communication in publications and consistency in databases. SUMMARY Genome mapping can detect aneuploidy, balanced and unbalanced structural variation, as well as copy number changes. The Standing Committee for the International System for Human Cytogenomic Nomenclature (ISCN) recognised there was a need for a specific nomenclature for genome mapping that encompasses the range of abnormalities detected by this technique. This paper explains the general principles of the nomenclature as well as giving specific ISCN examples for the different types of numerical and structural rearrangements.

Abstract
Complete trisomy 22 is a rare chromosomal condition that is incompatible with life. However, mosaic trisomy 22 usually has prolonged survival compatibility and may present a good prognosis depending on the tissues affected. Herein, we described a male patient with the occurrence of mosaic trisomy 22 associated with the inversion of chromosome 9, with karyotype 47, XY, inv (9) (p11q13), + 22 [5] / 46, XY, inv(9) (p11q13) [45] and arr 22q11.1 ~ q13.33(16,417008-51,219,009)x2 ~ 3. It is not possible to infer, in general, the clinical characteristics associated with mosaic trisomy 22. However, the patient presented common clinical features observed in reported cases (in parentheses the percentage observed comparing all reported cases): facial dysmorphia (100%), delay in motor development/growth (82%), cardiac abnormalities (73%), ear abnormalities (55%) and facial and/or body asymmetry (55%), in addition to hypotonia, skin spots, hypoplastic nails. Given the survival and quality of life associated with multidisciplinary treatment, it can be concluded that the patient has a good prognosis. Conclusively, we're presenting the occurrence of mosaic trisomy 22 and chromosome 9 inversion in the patient with favorable prognosis. Thus, this study proposed a guide which should be inserted in databases of rare genetic conditions to help genetic counselors define mosaic trisomy 22 diagnosis.

Abstract
OBJECTIVE The purpose of this study was to evaluate the performance of noninvasive prenatal testing (NIPT) for the detection of chromosomal aneuploidies and copy number variations (CNVs) in twin pregnancies. METHOD A cohort of 2010 women with twin pregnancies was recruited. 1331 patients opted for NIPT, and 679 patients opted for expanded NIPT (NIPT-plus). All high-risk patients were advised to undergo invasive prenatal diagnosis. All participants were followed up until 6 months after birth. RESULTS Twenty-two cases were predicted to have a high risk of chromosome abnormalities by NIPT, of which 14 pregnant women underwent invasive prenatal diagnosis. The 14 cases included 3 cases of trisomy 21, 1 case of trisomy 18, 1 case of trisomy 7, 2 cases of sex chromosome aneuploidies (SCAs), and 7 cases of CNVs, of which the confirmed cases numbered 2, 1, 0, 1, and 0, respectively. Twenty cases were predicted to have a high risk of chromosome abnormalities by NIPT-plus, of which 16 pregnant women underwent invasive prenatal diagnosis. The 16 cases included 1 case of trisomy 21, 1 case of trisomy 7, 7 cases of SCAs, and 7 cases of CNVs, of which were confirmed in 1, 0, 3, and 2, respectively. No false-negative result was reported during the follow-up period. CONCLUSION The NIPT/NIPT-plus has excellent performance in the detection of chromosome aneuploidies in twin pregnancies. But for CNVs, the effectiveness of NIPT is poor, and the NIPT-plus have a certain detection efficiency. It is worth noting that pre- and post-genetic counseling is especially important, and the chorionicity, mode of conception, clinical indications, and fetal fraction should be considered as influencing factors.

Abstract
A palette of copy number changes in long-term epilepsy-associated tumors (LEATs) have been reported, but the data are heterogeneous. To better understand the molecular basis underlying the development of LEATs, we performed array-comparative genomic hybridization analysis to investigate chromosomal imbalances across the entire genome in 8 cases of LEATs. A high number of aberrations were found in 4 patients, among which deletions predominated. Both whole-chromosome and regional abnormalities were observed, including monosomy 19, deletion of 1p, deletions of 4p, 12p, and 22q, and gain of 20p. The common altered regions are located mainly on chromosomes 19 and 4p, identifying genes potentially involved in biological processes and cellular mechanisms related to tumorigenesis. Our study highlights new genomic alterations and reinforces others previously reported, offering new molecular insights that may help in diagnosis and therapeutic decision-making.

Abstract
Electroplating sludge (ES) is a waste that is generated by the galvanization industry and is highly toxic because it contains heavy metals. This study examined the physiochemical properties of ES residue, the recovery of the present metals, and the reuse of these metals to add value to this residue and avoid environmental contamination through its inadequate disposal. The potential for leaching of ES was investigated using various tests, and a decrease in the germination speed of Lactuca sativa seeds and the appearance of chromosomal aberrations in the cytotoxicity tests were observed. The reduction of the pH and dynamic leaching conditions favor the leaching of ES heavy metals. An increase in the ES concentration in soil decreases the speed of germination and increases the number of chromosomal aberrations that are related to aneugenic phenomena that promote tumor development. Metals were recovered through solubilization, followed by selective precipitation. The recovery of heavy metals from ES decreased its toxicity by eliminating toxic components. The reuse of the metals in the electroplating process may reduce the cost of disposal of ES, thereby rendering it an economically and environmentally friendly alternative. The products that were galvanized using the recovered solution showed the best results in the corrosion test, thereby demonstrating the viability of the use of this solution in industrial galvanization.

Abstract
In the present study, we aimed to check whether uterine leiomyomas (ULs) with an apparently normal karyotype in vitro comprise "hidden" cell subpopulations with numerical chromosome abnormalities (heteroploid cells). A total of 32 ULs obtained from 32 patients were analyzed in the study. Each UL was sampled for in vivo and in vitro cytogenetic studies. Karyotyping was performed on metaphase preparations from the cultured UL samples. A normal karyotype was revealed in 20 out of the 32 ULs, of which 9 were selected for further study based on the good quality of the interphase preparations. Then, using interphase FISH with centromeric DNA probes, we analyzed the copy number of chromosomes 7 and 16 in 1,000 uncultured and 1,000 cultured cells of each selected UL. All of the ULs included both disomic cells representing a predominant subpopulation and heteroploid cells reaching a maximum frequency of 21.6% (mean 9.8%) in vivo and 11.5% (mean 6.1%) in vitro. The spectrum of heteroploid cells was similar in vivo and in vitro and mostly consisted of monosomic and tetrasomic cells. However, their frequencies in the cultured samples differed from those in the uncultured ones: while the monosomic cells decreased in number, the tetrasomic cells became more numerous. The frequency of either monosomic or tetrasomic cells both in vivo and in vitro was not associated with the presence of MED12 exon 2 mutations in the tumors. Our results suggest that ULs with an apparently normal karyotype consist of both karyotypically normal and heteroploid cells, implying that the occurrence of minor cell subpopulations with numerical chromosome abnormalities may be considered a characteristic of UL tumorigenesis. Different frequencies of heteroploid cells in vivo and in vitro suggest their dependence on microenvironmental conditions, thus providing a pathway for regulation of their propagation, which may be important for the UL pathogenesis.

Abstract
In this study, the toxic effects of potassium bromate (KBrO3) were tested on Allium cepa L. meristematic cells. In order to determine the toxic effect and dose relationship, KBrO3 toxicity was investigated at doses of 25, 50, and 100 mg/L. The toxic effects were evaluated by using cytogenetic, biochemical, anatomical, and physiological parameters, and serious damages were observed depending on the dose. Significant reductions in germination percentage, weight gain, and radicle length were observed in all KBrO3-treated groups compared with the control. Mitotic activity decreased in meristematic cells after KBrO3 application. and mitotic index was decreased by 1.8 times in 100 mg/L KBrO3-treated group compared with the control group. The frequencies of micronucleus and chromosomal abnormalities tested as cytogenetic parameters were significantly higher in the group treated with 100 mg/L KBrO3 than those in the control group. Fragment and sticky chromosome were the most common types of chromosomal abnormalities. Lipid peroxidation measured in terms of MDA content increased with increasing doses of KBrO3. The activities of catalase and superoxide dismutase as antioxidant enzymes were importantly changed in KBrO3-treated groups. Anatomical changes such as cell deformation, substance accumulation, cell wall thickening, and flattened nucleus were determined after KBrO3 application, and it was observed that these changes reached a maximum level at 100 mg/L dose of KBrO3. As a result, KBrO3 treatments were been found to cause physiological, biochemical, cytogenetic, and anatomically toxic effects in meristematic cells of A. cepa, a eukaryotic model organism. The versatile toxicity induced by KBrO3 increased depending on the dose and reached a maximum level at 100 mg/L.

Abstract
Human embryos generated in vitro have a high incidence of chromosomal abnormalities that negatively affect pregnancy rate. Embryos generated in vitro secrete extracellular vesicles (EVs) into the culture medium that could be used potentially as indicators of embryo competence. This research aimed to evaluate the concentration and size of EVs and their gDNA content as an indicator of developmental competence in human embryos. Human embryos generated by intracytoplasmic sperm injection (ICSI) were classified morphologically as of either TOP, FAIR or POOR quality. Culture medium and developmentally arrested embryos (which were not able to be used for embryo transfer) were collected. Microvesicles, exosomes (MV/Exo) and apoptotic bodies (ABs) were isolated from culture medium. Nanoparticle tracking analysis (NTA) and array comparative genomic hybridization (aCGH) analysis were performed to evaluate EVs and their gDNA content. From NTA, the diameter (mean) of MVs/Exo from TOP quality embryos was higher (112.17 nm) compared with that of FAIR (108.02) and POOR quality embryos (102.78 nm) (P < 0.05). aCGH analysis indicated that MVs/Exo and ABs carried gDNA with the presence of 23 chromosome pairs. However, when arrested embryos were compared with their respective MVs/Exo and ABs, the latter had an increased rate of chromosomal abnormalities (24.9%) compared with embryos (8.7%) (P < 0.05). In conclusion, the size of EVs from culture medium might be an alternative for evaluating competence of human embryos, however more studies are needed to validate the use of gDNA from EVs as an indicator of embryo competence.

Abstract
OBJECTIVES To investigate the incidence of the single umbilical artery (SUA) malformation and postpartum outcomes in a retrospective analysis of 781 fetuses. MATERIALS AND METHODS This retrospective analysis included 781 pregnant women carrying singleton fetuses diagnosed with SUA at Gansu Provincial Maternal and Child-care Hospital between 2013 and 2019. Detailed data on maternal and fetal characteristics and postpartum outcomes were obtained. RESULTS In total, 624 (79.9 %) fetuses were diagnosed with isolated SUA and 157 (20.1 %) fetuses had SUA together with other structural and/or chromosome abnormalities. The highest incidence of malformation was found in the urinary system, followed by the cardiovascular system and digestive system. The incidence of SUA was 59.1 % on the right side and 40.9 % on the left side. Fetuses with SUA and other abnormalities tended to have a lower mean birth weight (3061 g vs 3201 g, p < 0.01), but no difference in the rate of preterm delivery was noted. CONCLUSIONS After a diagnosis of SUA, structural observation of the fetus is required. The urinary, cardiovascular and digestive systems should be the focus of observation. If relevant malformations are found, then genetic testing must be performed. With isolated SUA, dynamic monitoring of biological indicators is recommended for lower birth weight, but genetic testing is not recommended.

Abstract
The recent publication of a study into the contribution of embryo chromosomal abnormalities in recurrent pregnancy loss (RPL) affords the opportunity to revisit the hypothesis that women with an aneuploid pregnancy loss have a better chance of a successful pregnancy next time than women with a chromosomally normal loss. A previous miscarriage with an abnormal karyotype (unrelated to a parental chromosome rearrangement) should not be viewed as a marker of an increased likelihood of aneuploidy in a subsequent pregnancy; it is (counterintuitively) likely to be indicative of a reduced risk of clinical miscarriage (with a higher proportion of aneuploid products) and an excellent chance for the live birth of the next pregnancy. Each couple should be treated on their own merits and with appropriate investigations performed where indicated; caution should be advised regarding offering preimplantation genetic testing for aneuploidy (PGT-A).

Abstract
BACKGROUND We analyzed the cytogenetic characteristics of a representative population of young adults with de novo acute myéloblastic leukemia (AML) treated in a single center institution. METHODS Patients with de novo AML included were aged between 20 and 60 years. Cytogenetic analysis was done at diagnosis. Twenty cells were analyzed, although examination of lower numbers of metaphases was also acceptable if an abnormal clone was detected. FINDINGS From 1/1/04 to 31/12/2014, among 1315 adult patients, 1055 (80%) patients were aged between 20 and 60 years. Karyotype was done in 927 (88%) patients and cytogenetic analysis failed in 32 cases (3·4%). Clonal abnormalities were observed in 520 (58%) patients. 175 (19·5%) were classified in the favorable group, 609 were in the intermediate group and 111 (12·5%) were in the adverse group. The most frequent chromosomal abnormality observed was t(8;21) in 112 (12·5%). Thirty three (3·7%) patients had t(15;17) and 30 (3·3%) had inv16, trisomy 8 was found in 47 (5·2%), 11q23 rearrangements in 32 (3·6%), 67 (7·4%) had a complex karyotype, -5/del(5q) and -7/del(7q) were seen in, respectively, 11(1%) and 27 (3%). Monosomy occurred in 115 (13%) patients, 70 (8%) responded to the definition of monosomal karyotypes. INTERPRETATION This is the largest study done in Morocco, Africa and Middle East. Epidemiological studies involving different ethnic populations and geographic regions of the world should help unfold the true nature of environmental and genetic interplay in the development of AML. Our cytogenetic profile reveals some particularities when compared to other populations; it does not seem to be similar neither to eastern or western countries.

Abstract
Hepatocellular carcinoma (HCC), the most common form of liver cancer, represents a health problem in hepatic viruses-eradicating era because obesity, type 2 diabetes, and nonalcoholic steatohepatitis (NASH) are considered emerging pathogenic factors. Metabolic disorders underpin mitotic errors that lead to numerical and structural chromosome aberrations in a significant proportion of cell divisions. Here, we review that genomically unstable HCCs show evidence for a paradoxically DNA damage response (DDR) which leads to ongoing chromosome segregation errors. The understanding of DDR induced by defective mitoses is crucial to our ability to develop or improve liver cancer therapeutic strategies.

Abstract
PURPOSE Infertility is estimated to affect 15% of couples, having chromosome abnormalities an important role in its etiology. The main objective of this work was to access the reproductive success of ART in infertile couples with chromosomal abnormalities comparing to a control group with normal karyotype. METHODS A 7-year retrospective karyotype analysis of infertile couples was done. Data regarding type of infertility, couples' ages, ART performed, and their reproductive success were obtained. Adjusted odds ratio (OR) were used to estimate magnitude of association between the reproductive success and the different groups. RESULTS We found a prevalence of 7.83% of chromosome abnormalities in our population (233 couples out of 2989). Chromosomal anomalies were found in 82 men (34.75%) and 154 women (65.25%), with low-grade mosaicism being the most prevalent (50.85%), followed by autosomal translocations (17.37%) and sex chromosomes abnormalities (13.56%). Only 2359 couples were treated with ART. There was a non-significant lower reproductive success rate in the cases (OR = 0.899, p = 0.530) with IVF providing the higher success rate. In general, female carriers of chromosome anomalies had a higher success rate, although not significant. CONCLUSION Although the differences regarding success rate between groups were not found statistically significant, we still advocate that cytogenetic analysis should be performed routinely in all infertile couples namely before ART. This might help deciding the best treatment options including Preimplantation Genetic Testing for aneuploidies or structural rearrangements and minimize the risk of transmission of anomalies to the offspring.

Abstract
AIM: The goals of this paper are: to report the incidence of AML in elderly, to describe cytogenetic characteristics of this population, to observe rare and novel cytogenetic abnormalities and lastly, to compare our finding with that previously reported in the literature. METHODS: We conducted a retrospective analysis of 283 patients with acute myeloid leukaemia (AML) treated in our unit, we will report the incidence of AML in elderly, describe cytogenetic characteristics of this population, observe rare and novel cytogenetic abnormalities and compare our finding with that previously reported in the literature. RESULTS: Among the 283 patients, 157 (54.4%) patients performed the karyotype, the cytogenetic analysis failed in 17 cases (11%). Prognostic group distribution was found to be favorable in 8 patients (6%) with 6 cases of t (8; 21) and 2 cases of inv (16), intermediate group in 94 patients (67%), including 58 cases (41,5%) with a normal karyotype, and an unfavorable group in 38 patients (27%) including complex karyotype (15%), -5 or del 5q (3%), -7 or del 7q (3.5%), t (9; 22) (2%). Some rare anomalies were observed. CONCLUSION: However, the occurrence of a complex karyotype was more frequent than younger patients. In our unit, elderly benefit from supportive care, our study shows that it is a heterogeneous group and our treatment approach have to change especially for the patient from favourable risk group who can benefit from intensive chemotherapy. We have to improve our diagnosis with including molecular genetics that provides a documented substrate for a thoughtfully considered treatment plan.

Abstract
PURPOSE The aim of the study was to assess cytogenetic and embryoscopic characteristics in subsequent miscarriages of spontaneous pregnancy losses (SPL) and recurrent pregnancy losses (RPL). METHODS A retrospective cohort of 75 women was affected by repeated pregnancy loss. Of those, 34 had SPL, 24 primary RPL, and 17 secondary RPL. Ploidy status and morphology was analyzed by transcervical embryoscopic examination of the embryo and cytogenetic analysis of the chorionic villi in subsequent miscarriages. RESULTS Similar rates of recurrent ploidy status were observed between first and second miscarriage in SPL and RPL (82.4% recurrent ploidy status in SPL, p > 0.999; 73% recurrent ploidy status in RPL, p = 0.227). No difference was found regarding recurrent abnormal morphology between SPL and RPL (p = 0.092). However, secondary RPL resulted significantly more often in recurrent abnormal morphology compared to primary RPL (p = 0.004). CONCLUSIONS High rates of recurrent normal/abnormal karyotypes were observed in all groups with a majority of embryos presenting with recurrent abnormal morphology. Secondary RPL presented significantly more often with recurrent abnormal morphology compared to primary RPL. These findings offer prognostic information for the affected patient and might impact treatment choice.

Abstract
Fluorescence in situ hybridization (FISH) has a wide spectrum of applications in current molecular cytogenetic and cancer research. This is a unique technique that can be used for chromosomal DNA analysis in all cell types, at all stages of the cell cycle, and at molecular resolution. Recent developments in microscopy and imaging systems have allowed quantification of digital FISH images (quantitative FISH or QFISH) and have provided a new way for molecular cytogenetic analysis at single-cell level. QFISH can be applied for studying chromosome imbalances in interphase nuclei or metaphase spreads, measuring relative DNA content at chromosomal loci and identifying parental origin of homologous chromosomes. Here, a QFISH protocol suitable for the majority of DNA probes using the popular US National Institute of Health developed ImageJ software is described.

Abstract
Few studies have examined the value of cytogenetic studies with flow cytometry (FC) in lymph node/extranodal tissue biopsies with suspected lymphoma. To evaluate this, G-banded karyotyping and/or fluorescence in situ hybridization (FISH) with FC immunophenotyping were performed on 185 lymph node or extranodal tissue biopsy specimens with suspected lymphoma. Complete cytogenetic analysis of lymph node/extranodal tissue was successful in 174 cases (94.1%) and 57.5% demonstrated chromosomal abnormalities. In 116 malignant lymphoma cases, 83.8% showed abnormalities. In 74 B cell lymphomas (B-NHL), abnormalities were more frequent in lymph node/extranodal tissues than in bone marrow by conventional cytogenetics (CC, 97.2 vs 26.1%), FISH (70.6 vs 17.6%), and FC (98.6 vs 28.4%). Three B-NHL diagnoses were confirmed by re-biopsy of lymph nodes due to the presence of abnormalities in the first biopsy, but no evidence of malignancy in pathological, FC, or IgH/TCR gene rearrangement analyses. In 29 T cell lymphomas (T-NHL), abnormalities were more frequent in lymph nodes than in bone marrow by CC (67.9 vs 21.4%) and FC (75.9 vs 27.6%) analyses. As expected, in 13 Hodgkin lymphoma cases, abnormalities were more frequent in lymph nodes than bone marrow by CC (41.7 vs 16.7%) and FC (30.8 vs 7.7%) analyses. In 56 reactive lymphoid hyperplasias (RLH), 7.1% had conventional clonal cytogenetic abnormalities. Two of these patients died of disease progression and two had their pathological diagnosis revised after the second review. These findings indicate that cytogenetic analysis combined with FC in lymph node/extranodal tissue biopsies can provide critical information in the auxiliary diagnosis of lymphoma.

Abstract
Klinefelter syndrome (KS) is one of the most common genetic causes of male infertility. This condition is associated with much comorbidity and with a lower life expectancy. The aim of this review is to explore more in depth cardiovascular and metabolic disorders associated to KS. KS patients have an increased risk of cerebrovascular disease (standardized mortality ratio, SMR, 2.2; 95% confidence interval, CI, 1.6-3.0), but it is not clear whether the cause of the death is of thrombotic or hemorrhagic nature. Cardiovascular congenital anomalies (SMR, 7.3; 95% CI, 2.4-17.1) and the development of thrombosis or leg ulcers (SMR, 7.9; 95% CI, 2.9-17.2) are also more frequent in these subjects. Moreover, cardiovascular abnormalities may be at least partially reversed by testosterone replacement therapy (TRT). KS patients have also an increased probability of endocrine and/or metabolic disease, especially obesity, metabolic syndrome and type 2 diabetes mellitus. The effects of TRT on these abnormalities are not entirely clear.

Abstract
In order to contribute to the knowledge of type and frequency of chromosome abnormalities in early pregnancy losses, we analyzed the cytogenetic results from a large series of first trimester miscarriages, using a diagnostic approach with a high success rate and no maternal contamination. A total of 1,119 consecutive chorionic villi samples were obtained before evacuation, and karyotypes were prepared after short-term culture (STC). In 603 samples, a long-term culture (LTC) was also performed. The overall and individual frequencies of the different types of chromosome abnormalities were established, including placental mosaicisms, and their relationship with maternal age and gestational weeks was assessed. An abnormal karyotype was detected in 70.3% of the samples. Single autosomal trisomy was the most frequent abnormality (64.6% of the abnormal cases), followed by triploidy (13.1%) and monosomy X (10.4%). Chromosome rearrangements were found in 5.2%, combined abnormalities in 8.9%, and placental mosaicism in 3.5% of the cases with STC and LTC performed. Individual trisomies behaved differently with respect to maternal age and intrauterine survival. Due to the combination of STC and LTC, our study offers reliable information on the incidence and type of chromosome abnormalities and placental mosaicism in miscarriages and contributes to define the cytogenetic implication in their etiology.

Abstract
Klinefelter Syndrome (KS) is characterized by an extreme heterogeneity in its clinical and genetic presentation. The relationship between clinical phenotype and genetic background has been partially disclosed; nevertheless, physicians are aware that several aspects concerning this issue are far to be fully understood. By improving our knowledge on the role of some genetic aspects as well as on the KS, patients' interindividual differences in terms of health status will result in a better management of this chromosomal disease. The aim of this review is to provide an update on both genetic and clinical phenotype and their interrelationships.

Abstract
This study aimed to investigate whether occupational and environmental exposures, lifestyle, family, and medical history are associated with chronic lymphocytic leukemia (CLL) risk and its chromosomal abnormalities. The study included 138 CLL cases and 141 age- and sex-matched controls. Information data were collected through in-person interviews from cases and controls. Cytogenetic analysis was performed on CLL bone marrow cells. Positive associations were found between CLL and cancer family history, smoking, pneumonia, and exposure to petroleum, metals, pesticides/chemical fertilizers, detergents, and medical radiation. Chromosome deletions of 11q and 13q were more frequent in patients exposed to pesticides and rubber, respectively. This study investigated for the first time specific risk factors in relation to CLL aberrations and presented positive correlations. Moreover, it indicates the possible involvement of specific occupational and lifestyle risk factors in the onset of CLL.

Abstract
Background The accurate identification of cytogenetic abnormalities in multiple myeloma (MM) has become more important over recent years for the development of new diagnostic and prognostic markers. In this study, we retrospectively analyzed the cytogenetic aberrations in MM cases as an initial assessment in a single institute. Methods We reviewed the cytogenetic results from 222 patients who were newly diagnosed with MM between January 2000 and December 2015. Chromosomal analysis was performed on cultured bone marrow samples by standard G-banding technique. At least 20 metaphase cells were analyzed for karyotyping. Results Clonal chromosome abnormalities were detected in 45.0% (100/222) of the patients. Among these results, 80 cases (80.0%) had both numerical and structural chromosome abnormalities. Overall hyperdiploidy with structural cytogenetic aberrations was the most common finding (44.0%), followed by hypodiploidy with structural aberrations (28.0%). Amplification of the long arm of chromosome 1 and -13/del(13q) were the most frequent recurrent abnormalities, and were detected in 50 patients (50.0%) and 40 patients (40.0%) with clonal abnormalities, respectively. The most common abnormality involving 14q32 was t(11;14)(q13;q32), which was observed in 19 cases. Conclusion These findings demonstrate that myeloma cells exhibit complex aberrations regardless of ploidy, even from a single center in Korea. Conventional cytogenetic analysis should be included in the initial diagnostic work-up for patients suspected of having MM.

Abstract
Mouse embryonic stem (ES) cells are widely used in early development studies and for transgenic animal production; however, a stable karyotype is a prerequisite for their use. We derived 32 ES cell lines of outbred mice (129 × BALB (1B), C57BL × 1B, and DD × 1B F1 hybrids). Pluripotency was assessed by utilizing stem-cell-marker gene expression, teratoma formation assays and the formation of chimeras. It was shown that only 21 of the 32 ES cell lines had a diploid modal number of chromosomes of 40. In these lines, the percentage of diploid cells varied from 30.3 to 78.9 %, and trisomy of chromosomes 1, 8 and 11 was observed in some cells in 16.7, 36.7 and 20.0 % of the diploid ES cell lines, respectively. Some cells had trisomy of chromosomes 6, 9, 12, 14, 18 and 19. In situ hybridization with an X chromosome paint probe revealed that 7 of the 11 XX-cell lines had X chromosome rearrangements in some cells. Analysis of the methylation status of the Dlk1-Dio3 locus showed that imprinting was altered in 4 of the 18 ES cell lines. Thus, mouse ES cell lines are prone to chromosome abnormalities even at early passages. Therefore, routine cytogenetic and imprinting analyses are necessary for ES cell characterization.

Abstract
Male infertility is the cause in half of all childless partnerships. Numerous factors contribute to male infertility, including chromosomal aberrations and gene defects. Few data exist regarding the association of these chromosomal aberrations with male infertility in Arab and North African populations. We therefore aimed to evaluate the frequency of chromosomal aberrations in a sample of 476 infertile men with non-obstructive azoospermia (n=328) or severe oligozoospermia (n=148) referred for routine cytogenetic analysis to the department of cytogenetics of the Pasteur Institute of Tunis. The overall incidence of chromosomal abnormalities was about 10.9%. Out of the 52 patients with abnormal cytogenetic findings, sex chromosome abnormalities were observed in 42 (80.7%) including Klinefelter syndrome in 37 (71%). Structural chromosome abnormalities involving autosomes (19.2%) and sex chromosomes were detected in 11 infertile men. Abnormal findings were more prevalent in the azoospermia group (14.02%) than in the severe oligozoospermia group (4.05%). The high frequency of chromosomal alterations in our series highlights the need for efficient genetic testing in infertile men, as results may help to determine the prognosis, as well as the choice of an assisted reproduction technique. Moreover, a genetic investigation could minimize the risk of transmitting genetic abnormalities to future generations.

Abstract
Fetal malformations are very frequent in industrialized countries. Although advanced maternal age may affect pregnancy outcome adversely, 80%-90% of fetal malformations occur in the absence of a specific risk factor for parents. The only effective approach for prenatal screening is currently represented by an ultrasound scan. However, ultrasound methods present two important limitations: the substantial absence of quantitative parameters and the dependence on the sonographer experience. In recent years, together with the improvement in transducer technology, quantitative and objective sonographic markers highly predictive of fetal malformations have been developed. These markers can be detected at early gestation (11-14 wk) and generally are not pathological in themselves but have an increased incidence in abnormal fetuses. Thus, prenatal ultrasonography during the second trimester of gestation provides a “genetic sonogram”, including, for instance, nuchal translucency, short humeral length, echogenic bowel, echogenic intracardiac focus and choroid plexus cyst, that is used to identify morphological features of fetal Down’s syndrome with a potential sensitivity of more than 90%. Other specific and sensitive markers can be seen in the case of cardiac defects and skeletal anomalies. In the future, sonographic markers could limit even more the use of invasive and dangerous techniques of prenatal diagnosis (amniocentesis, etc.).

Abstract
BACKGROUND The infertility is an important health problem, affecting about 15% of couples. The important role of genetic factors in pathogenesis of infertility is now increasingly recognized. The value of karyotyping women in the routine work-out of couples referred for sterility has long been recommended. OBJECTIVE The aim of this study was to define the frequency of all chromosomal aberrations among women which referred to our department due to infertility during the 21-year period. MATERIALS AND METHODS In this 21-year retrospective study, for the first time, we investigated 896 women which referred to our department due to infertility during 1986 to 2006. For chromosome analysis, heparinized peripheral blood samples were cultured, harvested and banded according to standard methods. RESULTS Out of 896 patients, 710 patients (79.24%) had a normal karyotype, and 186 patients (20.76%) showed abnormal karyotype. Among the abnormal ones 48 patients (25.81%) showed Turner's syndrome (45,X), and 45 patients (24.19%) were sex reversal with 46,XY karyotype. The rest of 93 patients (50%) revealed a wide range of chromosome abnormalities. CONCLUSION Our results emphasized the importance of the standard cytogenetic methods in assessing the genetic characteristics of infertile females, which allows detecting a variety of somatic chromosome abnormalities, because some of these may interfere with the success of reproduction.
