Abstract

Genomic DNA from five previously unreported patients with glycerol kinase deficiency (GKD), dystrophic myopathy, and adrenal insufficiency were studied with genomic probes and cDNA probes for the Duchenne muscular dystrophy (DMD) locus. These individuals, together with those reported by ourselves and others, show that patients with a contigous gene syndrome involving the DMD, GK, and adrenal hypoplasia congenita (AHC) loci have a broader distribution of microdeletion breakpoints than those observed among patients with classical DMD. This study demonstrates the use of the DMD cDNA probes to delineate the centromeric deletion breakpoints for patients with Xp21 microdeletions extending beyond the DMD locus. It also shows the practical diagnostic application of the DMD cDNA probes when the diagnosis of GKD is entertained in a patient with known DMD and only DNA is available for study.
