The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and arginine. This variant is present in population databases (rs545819982, ExAC 0.04%). This variant has been observed in individual(s) with clinical suspicion of limb-girdle muscular dystrophy (PMID: 30564623). ClinVar contains an entry for this variant (Variation ID: 290462). 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: "Not Available"; Align-GVGD: "Class C15"). 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.
