Invitae | RCV002608418 | SCV002956166 | uncertain significance | Infantile-onset X-linked spinal muscular atrophy | 2023-08-11 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals affected with UBA1-related conditions. 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. 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 tolerated. ClinVar contains an entry for this variant (Variation ID: 1913709). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces aspartic acid, which is acidic and polar, with alanine, which is neutral and non-polar, at codon 874 of the UBA1 protein (p.Asp874Ala). |
