Abstract

Trisomy 21 mongolism and D/D translocation occurred in the same individual. To our knowledge, this is the second case of this phenomenon. Three additional members of this patient's family were found to be D/D translocation carriers. Four additional instances in which these two abnormalities are associated within a single family are found in the literature. It is suggested that this association may well be significant and is worthy of further study.
