This variant is present in population databases (rs568432780, gnomAD 0.2%). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 48 of the SIRT1 protein (p.Pro48Leu). 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: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. (less)
