Genes affected

ELANE (HGNC:3309): (elastase, neutrophil expressed) Elastases form a subfamily of serine proteases that hydrolyze many proteins in addition to elastin. Humans have six elastase genes which encode structurally similar proteins. The encoded preproprotein is proteolytically processed to generate the active protease. Following activation, this protease hydrolyzes proteins within specialized neutrophil lysosomes, called azurophil granules, as well as proteins of the extracellular matrix. The enzyme may play a role in degenerative and inflammatory diseases through proteolysis of collagen-IV and elastin. This protein also degrades the outer membrane protein A (OmpA) of E. coli as well as the virulence factors of such bacteria as Shigella, Salmonella and Yersinia. Mutations in this gene are associated with cyclic neutropenia and severe congenital neutropenia (SCN). This gene is present in a gene cluster on chromosome 19. [provided by RefSeq, Jan 2016]

This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 126 of the ELANE protein (p.Ser126Leu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with cyclic neutropenia and severe congenital neutropenia (PMID: 11001877, 14962902, 16079102, 16737875, 18611981, 20582973, 22758217, 23463630). It has also been observed to segregate with disease in related individuals. This variant is also known as p.Ser97Leu. ClinVar contains an entry for this variant (Variation ID: 16745). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on ELANE function (PMID: 16551967, 26567890). For these reasons, this variant has been classified as Pathogenic. -
