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]

Variant summary: FOXRED1 c.1054C>T (p.Arg352Trp) results in a non-conservative amino acid change located in the FAD dependent oxidoreductase domain (IPR006076) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2.4e-05 in 250006 control chromosomes (gnomAD). c.1054C>T has been reported in the literature in individuals affected with Mitochondrial Complex 1 Deficiency, Nuclear Type 19 (e.g. Fassone_2010, Hu_2021). These data indicate that the variant is likely to be associated with disease. Publications also reported experimental evidence evaluating an impact on protein function, and demonstrated reduced complex I activity (e.g. Fassone_2010, Formosa_2015). The following publications have been ascertained in the context of this evaluation (PMID: 20858599, 33613441, 25678554). ClinVar contains an entry for this variant (Variation ID: 31048). Based on the evidence outlined above, the variant was classified as pathogenic. -

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 352 of the FOXRED1 protein (p.Arg352Trp). This variant is present in population databases (rs387907087, gnomAD 0.02%). This missense change has been observed in individual(s) with clinical features of mitochondrial complex I deficiency (PMID: 20858599, 33613441). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 31048). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on FOXRED1 protein function. Studies have shown that this missense change alters FOXRED1 gene expression (PMID: 20858599). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
