JAGN1

Chr 3AR

jagunal vesicle mediated transporter 1

Also known as: GL009, SCN6

This endoplasmic reticulum transmembrane protein regulates vesicle-mediated transport and is essential for neutrophil differentiation, survival, and function including defense against fungal pathogens. Mutations cause severe congenital neutropenia with autosomal recessive inheritance, typically presenting in the neonatal period with recurrent infections.
