Genes affected
FDX2 (HGNC:30546): (ferredoxin 2) This gene encodes a member of the ferredoxin family. The encoded protein contains a 2Fe-2S ferredoxin-type domain and is essential for heme A and Fe/S protein biosynthesis. Mutation in FDX1L gene is associated with mitochondrial muscle myopathy.

Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeAug 16, 2022This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 178 of the FDX2 protein (p.Val178Met). This variant is present in population databases (rs139721557, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with FDX2-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). 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. -
