Abstract:	Complex glycerol kinase deficiency is a contiguous gene syndrome that involves deletion of the glycerol kinase (GK) gene along with the loci for Duchenne muscular dystrophy (DMD) and/or adrenal hypoplasia congenita (AHC). The deletion breakpoints in these patients allowed identification of the critical regions for the GK and AHC genes, and both were identified using a positional cloning strategy. In addition to complex glycerol kinase deficiency, there are also two distinct phenotypes characterizing isolated glycerol kinase deficiency, the juvenile and benign forms. The juvenile form has onset in the first weeks to years of life with episodic decompensation. These episodes can be prevented or at least reduced in number by the use of a reduced-fat and therefore reduced-glycerol diet. Other families exhibit the benign form of isolated glycerol kinase deficiency. The affected individuals within these families have the biochemical features of this disorder but are asymptomatic.
