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.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.35).
BP6
Variant 4-150277993-C-T is Benign according to our data. Variant chr4-150277993-C-T is described in ClinVar as Benign. ClinVar VariationId is 540415.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=0.882 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00328 (500/152304) while in subpopulation AFR AF = 0.0108 (448/41564). AF 95% confidence interval is 0.00995. There are 4 homozygotes in GnomAd4. There are 215 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 4 AR gene
