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.

In summary, this variant has uncertain impact on JAGN1 function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with a JAGN1-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with arginine at codon 58 of the JAGN1 protein (p.Gly58Arg). The glycine residue is moderately conserved and there is a moderate physicochemical difference between glycine and arginine. -
