Multifocal gastric adenocarcinoma in a patient with LRBA deficiency

BACKGROUND Lipopolysaccharide-responsive, beige-like anchor protein (LRBA) deficiency is characterized by primary immunodeficiency and autoimmunity. Cancer may present another feature of LRBA deficiency. We describe a case history of a young adult with LRBA deficiency and two independent malignancies. METHODS Family-trio whole exome sequencing with unbiased phenotype ontology approach was use...

Agammaglobulinaemia despite terminal B-cell differentiation in a patient with a novel LRBA mutation

Mutations in lipopolysaccharide-responsive vesicle trafficking, beach and anchor-containing protein (LRBA) cause immune deficiency and inflammation. Here, we are reporting a novel homozygous mutation in LRBA allele in 7-year-old Omani boy, born to consanguineous parents. He presented with type 1 diabetes, autoimmune haematological cytopenia, recurrent chest infections and lymphocytic interstiti...

Deleterious mutations in LRBA are associated with a syndrome of immune deficiency and autoimmunity.

Most autosomal genetic causes of childhood-onset hypogammaglobulinemia are currently not well understood. Most affected individuals are simplex cases, but both autosomal-dominant and autosomal-recessive inheritance have been described. We performed genetic linkage analysis in consanguineous families affected by hypogammaglobulinemia. Four consanguineous families with childhood-onset humoral imm...

Murine LRBA deficiency causes CTLA-4 deficiency in Tregs without progression to immune dysregulation

Inherited mutations in lipopolysaccharide-responsive beige-like anchor (LRBA) cause a recessive human immune dysregulation syndrome with memory B-cell and antibody deficiency (common variable immunodeficiency), inflammatory bowel disease, enlarged spleen and lymph nodes, accumulation of activated T cells and multiple autoimmune diseases. To understand the pathogenesis of the syndrome, C57BL/6 m...
