Genes affected
FASLG (HGNC:11936): (Fas ligand) This gene is a member of the tumor necrosis factor superfamily. The primary function of the encoded transmembrane protein is the induction of apoptosis triggered by binding to FAS. The FAS/FASLG signaling pathway is essential for immune system regulation, including activation-induced cell death (AICD) of T cells and cytotoxic T lymphocyte induced cell death. It has also been implicated in the progression of several cancers. Defects in this gene may be related to some cases of systemic lupus erythematosus (SLE). Alternatively spliced transcript variants have been described. [provided by RefSeq, Nov 2014]

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 46 of the FASLG protein (p.Pro46Leu). This variant is present in population databases (rs779382158, gnomAD 0.09%). This variant has not been reported in the literature in individuals affected with FASLG-related conditions. ClinVar contains an entry for this variant (Variation ID: 851854). 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"). 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. -
