Genes affected
MECR (HGNC:19691): (mitochondrial trans-2-enoyl-CoA reductase) The protein encoded by this gene is an oxidoreductase that catalyzes the last step in mitochondrial fatty acid synthesis. Defects in this gene are a cause of childhood-onset dystonia and optic atrophy. [provided by RefSeq, Mar 2017]
