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.

Autosomal recessive severe congenital neutropenia due to JAGN1 deficiency

Pathogenic:1Uncertain:1

Pathogenic, no assertion criteria provided	literature only	OMIM	Sep 01, 2014	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Apr 25, 2022	This variant, c.35_43del, results in the deletion of 3 amino acid(s) of the JAGN1 protein (p.Thr12_Gly14del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs752053703, gnomAD 0.002%). This variant has been observed in individual(s) with neutropenia (PMID: 25129144). ClinVar contains an entry for this variant (Variation ID: 156117). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
