Uniparental Disomy of Chromosome 4: A Case of Whole Chromosome UPD Presenting with LRBA Deficiency
J Clin Immunol. 2024 Sep 18;45(1):10. doi: 10.1007/s10875-024-01803-9. ABSTRACT PURPOSE: Lipopolysaccharide-responsive beige-like anchor protein (LRBA) encodes a widely expressed cytosolic protein that participates in polarized vesicle trafficking. Homozygous loss-of-function LRBA mutations can lead to immune deficiency due to the lack of immune regulation, classified as a part of Tregopathies. We present a case of a … Read more
