Therefore, it has been classified as a Variant of Uncertain Significance. This variant disrupts the p.Ala44 amino acid residue in SLC22A5. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 23963628, 28711408). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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 tolerated. This variant has not been reported in the literature in individuals affected with SLC22A5-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces alanine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 44 of the SLC22A5 protein (p.Ala44Glu).
