Genes affected

TNFRSF13C (HGNC:17755): (TNF receptor superfamily member 13C) B cell-activating factor (BAFF) enhances B-cell survival in vitro and is a regulator of the peripheral B-cell population. Overexpression of Baff in mice results in mature B-cell hyperplasia and symptoms of systemic lupus erythematosus (SLE). Also, some SLE patients have increased levels of BAFF in serum. Therefore, it has been proposed that abnormally high levels of BAFF may contribute to the pathogenesis of autoimmune diseases by enhancing the survival of autoreactive B cells. The protein encoded by this gene is a receptor for BAFF and is a type III transmembrane protein containing a single extracellular cysteine-rich domain. It is thought that this receptor is the principal receptor required for BAFF-mediated mature B-cell survival. [provided by RefSeq, Jul 2008]

Collection Method:clinical testing

The TNFRSF13C c.475C>T; p.His159Tyr variant (rs61756766) is reported in the literature in multiple individuals affected with various autoimmune diseases, including common variable immunodeficiency (CVID), non-Hodgkin lymphoma, and Sjogren syndrome (Abolhassani 2019, Hildebrand 2010, Kutukculer 2012, Losi 2005, Lougaris 2014, Papageorgiou 2015), but also in healthy controls (Losi 2005, Papageorgiou 2015). Additionally, several of the affected individuals also carried the p.Pro21Arg variant (Kutukculer 2012, Lougaris 2014), including one CVID family in which these two variants were confirmed to be on the same chromosome (Lougaris 2016). This variant is reported in ClinVar (Variation ID: 440345), and is found in the general population with an overall allele frequency of 0.56% (1575/280578 alleles, including 10 homozygotes) in the Genome Aggregation Database. The histidine at codon 159 is highly conserved, and computational analyses (SIFT, PolyPhen-2) predict that this variant is deleterious. Functional assays show an increase in immunoglobulin production compared to wild-type cells in vitro (Hildebrand 2010), and a reduced amount of protein on patient cells in combination with the p.Pro21Arg variant (Lougaris 2016). Due to conflicting information and the lack of information regarding the association with the p.Pro21Arg variant, the clinical significance of the p.His159Tyr variant alone or in combination with p.Pro21Arg in CVID remains uncertain. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
