[COMPREHENSIVE DIAGNOSTICS IN PATIENTS WITH GENOTYPE 47,XXY KLINEFELTER SYNDROME].

We undertook biochemical, hormonal, cytological analysis and sequencing CAG repetitions of androgen receptor gene in order to elucidate the cause of clinical polymorphism of Klinefelter syndrome. Elevated levels of LH (19.8 ± 4.2 E/l), FSH (22.7 ± 6.1 U/l), total cholesterol (6.8 ± 2.6 mmol/l), triglycerides (3.3 ± 1.0 mmol/l), and glucose (9.9 ± 3.8 mmol/l) suggested disturbances of lipid and carbohydrate metabolism. Two thirds of the patients had Klinfelter syndrome associated with mental retardation and psychic disorders. Patients with cleft palate and mental retardation and with psycho-social disorders had 45 and 43 CA G repetitions respectively, those without associations 38-40 repetitions. Increased frequency of CAG repetitions was directly proportional to the level ofpsychic development, social adaptation and professional activity but inversely proportional to the development of masculine sexual traits.
