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]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.004830122).
• BP6: Variant 17-74866908-C-T is Benign according to our data. Variant chr17-74866908-C-T is described in ClinVar as [Benign]. Clinvar id is 769224.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.932 is higher than 0.05.
