neutropenia—severe congenital—X-linked


Definition A haematopoietic disorder (OMIM:300299) characterised by maturational arrest of granulopoiesis at the level of promyelocytes with peripheral absolute neutrophil counts below 0.5 x 109/l and early onset of severe bacterial infections. 

Molecular pathology Defects of WAS, which encodes an effector protein for Rho-type GTPases that mediates actin filament reorganisation and formation of actin pedestals after infection by pathogenic bacteria, cause neutropenia—severe congenital—X-linked.
