Labcorp Genetics (formerly Invitae), Labcorp RCV002006938 SCV002294388 uncertain significance Amyotrophic lateral sclerosis type 1; Perry syndrome; Neuronopathy, distal hereditary motor, type 7B 2021-02-02 criteria provided, single submitter clinical testing This sequence change replaces alanine with glycine at codon 307 of the DCTN1 protein (p.Ala307Gly). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and glycine. 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 DCTN1-related conditions. This variant is present in population databases (rs759253635, ExAC 0.009%).
