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: PanelApp Australia, Orphanet, G2P, Labcorp Genetics (formerly Invitae)
• optic atrophy-ataxia-peripheral neuropathy-global developmental delay syndrome

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
