Genes affected

CD40LG (HGNC:11935): (CD40 ligand) The protein encoded by this gene is expressed on the surface of T cells. It regulates B cell function by engaging CD40 on the B cell surface. A defect in this gene results in an inability to undergo immunoglobulin class switch and is associated with hyper-IgM syndrome. [provided by RefSeq, Jul 2008]

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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt CD40LG protein function. ClinVar contains an entry for this variant (Variation ID: 575442). This variant has not been reported in the literature in individuals affected with CD40LG-related conditions. This variant is present in population databases (rs368691563, gnomAD 0.008%), including at least one homozygous and/or hemizygous individual. This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 110 of the CD40LG protein (p.Ser110Arg). -
