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
    Inheritance: AR Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: G2P, Orphanet, Labcorp Genetics (formerly Invitae)
