| Identified Mutation |
LEU156ARG; Holt et al. [Am. J. Hum. Genet. 46: 428 (1990)] found a heteroplasmic T-to-G transversion at nucleotide pair 8993 in a maternal pedigree which resulted in the change of a hydrophobic leucine to a hydrophilic arginine at position 156 in subunit 6 of mitochondrial H(+)-ATPase. The clinical symptoms varied in proportion to the percentage of mutant mtDNAs but the most common clinical presentation included neurogenic muscle weakness, ataxia, and retinitis pigmentosa, leading to the designation of NARP (551500). The insertion of an arginine in the hydrophobic sequence of ATPase 6 probably interferes with the hydrogen ion channel formed by subunits 6 and 9 of the ATPase, thus causing failure of ATP synthesis. Tatuch et al. [Am. J. Hum. Genet. 50: 852 (1992)] and Shoffner et al. [Neurology 42: 2168 (1992)] demonstrated that the nucleotide 8993 mutation can cause Leigh disease. |
