Genes affected

LRBA (HGNC:1742): (LPS responsive beige-like anchor protein) The protein encoded by this gene is a member of the WDL-BEACH-WD (WBW) gene family. Its expression is induced in B cells and macrophages by bacterial lipopolysaccharides (LPS). The encoded protein associates with protein kinase A and may be involved in leading intracellular vesicles to activated receptor complexes, which aids in the secretion and/or membrane deposition of immune effector molecules. Defects in this gene are associated with the disorder common variable immunodeficiency-8 with autoimmunity. Two transcript variants encoding different isoforms have been found for this gene.

The p.His571His variant (rs145812385) does not alter the amino acid sequence of the LRBA protein and computational splice site prediction algorithms do not predict a change in the nearest splice site or creation of a cryptic splice site (Alamut v2.10). This variant has not been reported in association with immunodeficiency in medical literature or in gene specific variation databases. This variant is listed in the Genome Aggregation Database (gnomAD) with a frequency of 0.01 percent in the European Non-Finnish population (identified on 130 out of 126,186 chromosomes), and has been reported to the ClinVar database (Variation ID: 284747). Based on these observations, the p.His571His variant is likely to be benign. -
