Duchenne muscular dystrophy, glycerol kinase deficiency, and adrenal insufficiency associated with Xp21 interstitial deletion

J Pediatr. 1986 Feb;108(2):189-92. doi: 10.1016/s0022-3476(86)80980-5.


We report an interstitial deletion in the short arm of the X chromosome in a 6-year-old boy with Duchenne muscular dystrophy, glycerol kinase deficiency, adrenal insufficiency, intermittent hypoglycemia, spasticity, psychomotor retardation, and growth delay. His mother also has this deletion in an X chromosome. From our findings, we propose that the human glycerol kinase locus and the human X-linked adrenal hypoplasia locus are in the Xp21 band.
