Novel Lipopolysaccharide-Responsive Vesicle Trafficking, Beach- and Anchor-Containing (LRBA) Gene Mutation Identified in a Pediatric Patient: A Case Report.

Homozygous mutations in the lipopolysaccharide-responsive vesicle trafficking, beach- and anchor-containing () gene lead to a syndrome characterized by early-onset hypogammaglobulinemia, autoimmunity, lymphoproliferation, and inflammatory bowel disease. This report describes a 10-year-old female who experienced three seizure episodes, including two generalized tonic-clonic seizures (GTCS) and one focal seizure, alongside septic shock. The patient had a history of recurrent respiratory tract infections, inflammatory bowel disease, multiple blood transfusions, lymphadenopathy, significant organomegaly, and hematological abnormalities, all consistent with an deficiency. This case highlights the critical need for prompt recognition and identification of gene mutations to enable timely management and improve patient outcomes.
