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 arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 156 of the FASLG protein (p.Arg156Gly). This variant is present in population databases (rs80358238, gnomAD 0.01%). This missense change has been observed in individual(s) with autosomal dominant autoimmune lymphoproliferative syndrome (PMID: 17605793). ClinVar contains an entry for this variant (Variation ID: 21212). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt FASLG protein function with a negative predictive value of 80%. Experimental studies have shown that this missense change affects FASLG function (PMID: 17605793). 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. -

The FASLG c.466A>G variant is predicted to result in the amino acid substitution p.Arg156Gly. This variant was reported in the heterozygous state in an individual with autoimmune lymphoproliferative syndrome (Reported as A530G, Bi et al. 2007. PubMed ID: 17605793). Additional functional studies showed that this variant produced a protein that bound to wild-type protein, but prevented it from effectively inducing apoptosis (Bi et al. 2007. PubMed ID: 17605793; Bleesing et al. 1993. PubMed ID: 20301287). This variant is reported in 0.010% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Although we suspect that this variant may be pathogenic, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
