Summary
A young female was diagnosed as having X-linked muscular dystrophy of the Duchenne type. Chromosome studies, including trypsin-Giemsa banding, Quinacrine fluorescence, and nucleolus organizer region (NOR) silver staining revealed an X-autosome reciprocal translocation t(X;21) (p21;p12). Utilizing both [3H] thymidine autoradiography and the BrdU-Hoechst 33258-Giemsa technique, lymphocytes and fibroblasts were found to show a preferential inactivation of the normal X suggesting the presence of a single mutant gene on the translocated X. This patient is one of seven reported cases of an X-linked muscular dystrophy associated with an X-autosome translocation. In all seven cases the exchange point in the X chromosome is in band p21 at or near the site of the Duchenne gene.
