IN 1960 Lejeune et al.1 noted a centric fusion of 2 13–15 chromosomes in the cells of a person with Klinefelter's syndrome, and in 1962 Walker and Harris2 , 3 reported several generations of a family with cases of similar translocation. In the study presented here, a family with a possible mosaicism for a similar translocation is described.
