Анализ сегрегации хромосом у носителей реципрокных транслокаций

Autosomal reciprocal translocations (ART) lead to an increased risk of imbalanced gametes formation due to pathological meiotic segregation. Segregation type was analyzed and theoretical segregation pattern was determined in 26 cleavage stage embryos in this article. A coincidence of theoretical and detectable segregation types was observed in more than 50 % of blastomeres in 73 % of cases. The data obtained may be used for personalized genetic counseling in families with high risks of recurrent spontaneous abortions, infertility or children with birth defects due to ART.
