Background. Klinefelter’s syndrome (KS) is the most common genetic cause of human male infertility asosieted with azoospemia in 10-15%. KS is due to the presence of one or more supernumerary X chromosomes. Most genes from the extra X undergo inactivation, but some escape and play a role in klinefelter pathogen. Objective of the study. to study the neurological and cytogenetic peculiarities of KS in infertile men in order to initiate measures to improve their quality of life. Material and Method. the study was performed on 110 men with infertility, selected during medical genetic counseling, having as selection criteria, lack of sperm in the ejaculate, elevated values of FSH and LH, the following phenotypic aspects: hypospadias, small testes, cryptorchidism, waist high and disproportionate, hypogonadism, gynecomastia, mental retardation, psychosocial problems. Results. The most common chromosomal abnormality diagnosed in the 33 patients with KS was homogeneous free trisomy 47,XXY (30 cases - 90.9%), followed by the forms: mosaic (47,XXY /46,XY: 1 case), polysomy X-Y (variant 48,XXYY: 1 case - and 49,XXXXY: 1 case). In most patients with variant 47,XXY the classical and mosaic form showed a mild to moderate mental retardation, language disorders with cognitive-verbal retardation, slow motor development, coordination disorders, immature behavior. In patients with variants 48,XXYY and 49,XXXXY, were ascertained moderate to severe mental retardation, severe cognitive-verbal retardation, behavioral problems. Conclusion. The diagnosis of the cytogenetic variant in patients with KS is of neurological importance, as the severity of the neurodevelopmental phenotype in subjects with KS is directly proportional to the number of the supernumerary X chromosome. |
