Familial multiple symmetric lipomatosis associated with the A8344G mutation of mitochondrial DNA

Neurology. 1998 Jul;51(1):258-60. doi: 10.1212/wnl.51.1.258.

Abstract

We describe familial multiple symmetric lipomatosis in a pedigree harboring the 8344 mutation in the tRNA(Lys) gene of mitochondrial DNA (mtDNA). The proband showed neuromuscular involvement but lacked the typical manifestations of myoclonic epilepsy and ragged-red fibers disease. The distribution of the mutation was unusual because the proportion of mutated genomes was higher in blood and lipomas than in muscle tissue.
