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.

Uncertain significance, criteria provided, single submitter	clinical testing	Fulgent Genetics, Fulgent Genetics	Apr 25, 2022	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Dec 01, 2023	This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 1231 of the LRBA protein (p.Ser1231Gly). This variant is present in population databases (rs749012995, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with LRBA-related conditions. ClinVar contains an entry for this variant (Variation ID: 581781). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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 LRBA c.3691A>G variant is predicted to result in the amino acid substitution p.Ser1231Gly. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.020% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/4-151773171-T-C). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
