Description

This sequence change replaces aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 389 of the SAG protein (p.Asp389Glu). This variant is present in population databases (rs199798289, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with SAG-related conditions. ClinVar contains an entry for this variant (Variation ID: 335073). 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. 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.
