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.

May 22, 2023

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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ATL3 protein function. ClinVar contains an entry for this variant (Variation ID: 576489). This variant has not been reported in the literature in individuals affected with ATL3-related conditions. This variant is present in population databases (rs574916292, gnomAD 0.01%). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 442 of the ATL3 protein (p.Arg442Gln). -
