title: [Karyotypes of spontaneous human abortuses and several aspects of their phenotypic presentation].
abstract: In all, 172 human spontaneous abortuses were examined: 75 cases from the 1st trimester of pregnancy (all were karyotyped), and 97 ones--from 2nd and 3rd trimesters (59 cases were karyotyped). 31 cases of chromosomal anomalies were revealed. The incidence of chromosomal anomalies among the 1st and 2--3rd trimesters of spontaneous abortuses was 40.0+/-7.5 and 1.0+1.0%, resp. The general incidence of chromosomal anomalies among this series of spontaneous abortuses was equal to 18.0+/-2.9%. The question of phenotypical manifestations of chromosomal aberrations in spontaneous abortuses is discussed. The influence of gene structure of aberrant chromosomes on phenotypes of abortuses is supposed.
