Genes affected
SLC25A46 (HGNC:25198): (solute carrier family 25 member 46) This gene encodes a mitochondrial solute carrier protein family member. It functions in promoting mitochondrial fission, and prevents the formation of hyperfilamentous mitochondria. Mutation of this gene results in neuropathy and optic atrophy.

Neuropathy, hereditary motor and sensory, type 6B Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpFeb 05, 2022This sequence change replaces threonine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 153 of the SLC25A46 protein (p.Thr153Asn). This variant is present in population databases (rs775286893, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with SLC25A46-related conditions. ClinVar contains an entry for this variant (Variation ID: 582594). 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. -
