[2 cases of partial trisomy 10p due to a paternal translocation t(10p;18)(p13;q23)].

Abstract

Two brothers trisomic for the distal two thirds of 10p are reported. Trisomy results from the malsegregation of a familial translocation rcp (10;18)(p13;q23) present in the father, a half-brother and the grand-father of the propositi. The phenotype is comparable to that of other 10p trisomic patients reported in the literature.
