An important gene associated with Severe Congenital Neutropenia 1 is ELANE (Elastase, Neutrophil Expressed), and among its related pathways/superpathways are Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins. and Complex I biogenesis. Affiliated tissues include neutrophil.
