The classic form of the 47 / XXY karyotype, the incidence of this syndrome is one in 500-1000 live male births. The incidence of 48 / XXYY male individuals with many phenotypic features of Klinefelter syndrome is extremely rare and occurs in 1: 18000 -1: 100.000 men. However, they differ from Klinefelter syndrome with serious behavioral problems, mental reterdation and susceptibility to psychiatric diseases [1 ]. A 38-year-old man, referred to our Medical Biology and Genetics laboratory for karyotype analysis with primary infertility.

Semen analysis demonstrated azoospermia In the psychiatric examination of the patient, whose IQ level was 90, language, learning and behavior disorder were diagnosed.
