Labcorp Genetics (formerly Invitae), Labcorp RCV003019913 SCV003327261 uncertain significance Amyotrophic lateral sclerosis type 1; Perry syndrome; Neuronopathy, distal hereditary motor, type 7B 2022-03-11 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 721 of the DCTN1 protein (p.Thr721Ala). 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. This variant has not been reported in the literature in individuals affected with DCTN1-related conditions. This variant is not present in population databases (gnomAD no frequency).
