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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 566349). This variant has not been reported in the literature in individuals affected with ATL3-related conditions. This variant is present in population databases (rs201256418, gnomAD 0.002%). This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 26 of the ATL3 protein (p.Pro26Ala). 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. -
