| Abstract: | Different parental translocations were observed in 11 out of 59 families where a child with Patau's syndrome was born. All cases, except for one with t(13; 18) (q14; q23) in the father, revealed the Robertsonian translocations. In most cases there were t(13; 14). The t(13; 15) and t(13; 13) translocations were detected in one mother each. The latter woman bore three babies with Patau's syndrome. One boy in this series had trisomy 13 and sporadic translocation t(2; 22) (q31; q13) simultaneously. |
