[Incidence of 47,XXY and 47,XYY karyotypes among the mentally ill who have committed antisocial acts].

A cytogenetic screening of 1868 mentally diseases criminals is performed. 5 man with abnormal karyotypes were found: 2 with the chromosome set 47,XXY; 1--with mosaicism 46,XY/47,XXY and 2--with karyotype 47,XYY. Total frequency of chromosome abnormalities was found to be 0.27% (XXY karyotype--0.16%, XYY--0.11%). Among tall mentally diseased criminals the frequency of XXY set was found to be 0.94%, and of XYY--1.89%. So among tall mentally diseased criminals the frequency of these abnormalities is higher. The frequency of karyotype abnormalities among mentally diseased criminals was not found to be higher than in total population.
