Genes affected
UQCC2 (HGNC:21237): (ubiquinol-cytochrome c reductase complex assembly factor 2) This gene encodes a nucleoid protein localized to the mitochondria inner membrane. The encoded protein affects regulation of insulin secretion, mitochondrial ATP production, and myogenesis through modulation of mitochondrial respiratory chain activity.
