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), LabcorpApr 29, 2018This sequence change replaces glutamine with histidine at codon 283 of the SLC25A46 protein (p.Gln283His). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and histidine. This variant is present in population databases (rs772739765, ExAC 0.003%). This variant has not been reported in the literature in individuals with SLC25A46-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; 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. -
