Genes affected

FDXR (HGNC:3642): (ferredoxin reductase) This gene encodes a mitochondrial flavoprotein that initiates electron transport for cytochromes P450 receiving electrons from NADPH. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Apr 2012]

FDXR Gene-Disease associations (from GenCC):

auditory neuropathy-optic atrophy syndrome
Inheritance: AR Classification: STRONG, SUPPORTIVE Submitted by: Orphanet, Labcorp Genetics (formerly Invitae), G2P
