Genes affected

FOXRED1 (HGNC:26927): (FAD dependent oxidoreductase domain containing 1) This gene encodes a protein that contains a FAD-dependent oxidoreductase domain. The encoded protein is localized to the mitochondria and may function as a chaperone protein required for the function of mitochondrial complex I. Mutations in this gene are associated with mitochondrial complex I deficiency. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Dec 2010]

Uncertain significance, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Dec 14, 2023	Variant summary: FOXRED1 c.7C>T (p.Arg3Trp) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 3.2e-05 in 250200 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.7C>T has been reported in the literature in an individual affected with ataxia (Ngo_2020). This report does not provide unequivocal conclusions about association of the variant with Leigh Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One submitter has cited a clinical-significance assessment for this variant to ClinVar after 2014 and has classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Mar 16, 2017	p.Arg3Trp (CGG>TGG):c.7 C>T in exon 1 of the FOXRED1 gene (NM_017547.3). The R3W missense substitution has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The amino acid change is non-conservative in that a positively charged Arginine residue is replaced by an uncharged Tryptophan residue. This change occurs at a position in the FOXRED1 protein that is not highly conserved, and multiple in-silico analyes predict that R3W is a benign sequence change. Therefore, based on the currently available information, it is unclear whether R3W is a disease-causing mutation or a rare benign variant. The variant is found in MITONUC-MITOP panel(s). -
