Genes affected

JAGN1 (HGNC:26926): (jagunal homolog 1) The protein encoded by this gene is a transmembrane protein. It functions in the early secretory pathway and is necessary for neutrophil differentiation and survival. Mutations in this gene result in severe congenital neutropenia. [provided by RefSeq, Oct 2014]

JAGN1 Gene-Disease associations (from GenCC):

autosomal recessive severe congenital neutropenia due to JAGN1 deficiency
