Genes affected

ATL3 (HGNC:24526): (atlastin GTPase 3) This gene encodes a member of a family of dynamin-like, integral membrane GTPases. The encoded protein is required for the proper formation of the network of interconnected tubules of the endoplasmic reticulum. Mutations in this gene may be associated with hereditary sensory neuropathy type IF. Alternatively spliced transcript variants that encode distinct isoforms have been described.

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. 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 disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with ATL3-related disease. This variant is present in population databases (rs776366099, ExAC 0.002%). This sequence change replaces leucine with arginine at codon 186 of the ATL3 protein (p.Leu186Arg). The leucine residue is highly conserved and there is a moderate physicochemical difference between leucine and arginine. -
