CME Review


To date, several germline mutations have been identified in the LRBA gene in patients suffering from a variety of clinical symptoms. These mutations abolish the expression of the LRBA protein, leading to autoimmunity, chronic diarrhea, B-cell deficiency, hypogammaglobulinemia, functional T-cell defects and aberrant autophagy. We review the clinical and laboratory features of patients with LRBA mutations and present five novel mutations in eight patients suffering from a multitude of clinical features.


Primary immunodeficiency disorders (PID) lipopolysaccharide responsive beige-like anchor protein (LRBA) common variable immunodeficiency (CVID) autoimmune disease (AID) chronic diarrhea (CD) hypogammaglobulinemia (HGG) organomegaly (OM) regulatory T-cells (Treg) cytotoxic T-lymphocyte-associated protein 4 (CTLA4) autophagy apoptosis
