ClinVar contains an entry for this variant (Variation ID: 430861). This variant has been observed in individual(s) with clinical features of SGPL1-related conditions (PMID: 28165343, 30517686, 31130284). It has also been observed to segregate with disease in related individuals. This variant is present in population databases (rs769259446, ExAC 0.006%). This sequence change replaces arginine with glutamine at codon 222 of the SGPL1 protein (p.Arg222Gln). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and glutamine. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Arg222 amino acid residue in SGPL1. Other variant(s) that disrupt this residue have been observed in individuals with SGPL1-related conditions (PMID: 28165339), which suggests that this may be a clinically significant amino acid residue. Experimental studies have shown that this variant affects SGPL1 protein function (PMID: 28165343).
