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]

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.75).
• BP6: Variant 19-851457-A-G is Benign according to our data. Variant chr19-851457-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 3030858.Status of the report is no_assertion_criteria_provided, 0 stars.
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.00748 (971/129764) while in subpopulation EAS AF= 0.0291 (101/3468). AF 95% confidence interval is 0.0254. There are 1 homozygotes in gnomad4. There are 507 alleles in male gnomad4 subpopulation. Median coverage is 26. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 971 AD gene.
