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 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 07, 2023This sequence change replaces phenylalanine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 17 of the JAGN1 protein (p.Phe17Leu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with JAGN1-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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. -
