Genes affected
SLC25A46 (HGNC:25198): (solute carrier family 25 member 46) This gene encodes a mitochondrial solute carrier protein family member. It functions in promoting mitochondrial fission, and prevents the formation of hyperfilamentous mitochondria. Mutation of this gene results in neuropathy and optic atrophy.
