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]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.95
