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]

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces isoleucine, which is neutral and non-polar, with asparagine, which is neutral and polar, at codon 485 of the FOXRED1 protein (p.Ile485Asn). This variant is present in population databases (rs770063137, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with FOXRED1-related conditions. ClinVar contains an entry for this variant (Variation ID: 452423). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1454T>A (p.I485N) alteration is located in exon 11 (coding exon 11) of the FOXRED1 gene. This alteration results from a T to A substitution at nucleotide position 1454, causing the isoleucine (I) at amino acid position 485 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
