RCV002700584 | SCV002998313 | uncertain significance | Amyotrophic lateral sclerosis type 1; Perry syndrome; Neuronopathy, distal hereditary motor, type 7B | 2022-02-19 | criteria provided, single submitter | clinical testing | 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. Experimental studies have shown that this missense change does not substantially affect DCTN1 function (PMID: 23143281). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamic acid amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This missense change has been observed in individual(s) with DCTN1-related conditions (PMID: 23143281). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 333 of the DCTN1 protein (p.Asp333Glu). |
