LAD with RAC2 deficiency

Defects in RAC2 are the cause of neutrophil immunodeficiency syndrome, that clinically resembles LAD1. Rac2 is part of the NADPH oxidase complex. Rac2 is necessary for the regulation of the actin cytoskeleton (chemotaxis and degranulation) and NADPH oxidase (superoxide production) function.
