Variant summary

Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PS1_Moderate PM1 PM2 PP3_Strong PP5_Moderate

The NM_001972.4(ELANE):​c.416C>G​(p.Pro139Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely pathogenic in UniProt.

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 Pathogenic. Variant got 12 ACMG points.

• PS1: Transcript NM_001972.4 (ELANE) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in UniProt
• PM1: In a domain Peptidase S1 (size 217) in uniprot entity ELNE_HUMAN there are 55 pathogenic changes around while only 2 benign (96%) in NM_001972.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.987
• PP5: Variant 19-855613-C-G is Pathogenic according to our data. Variant chr19-855613-C-G is described in ClinVar as [Pathogenic]. Clinvar id is 2138170.Status of the report is criteria_provided_single_submitter, 1 stars.

This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 139 of the ELANE protein (p.Pro139Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with congenital neutropenia and/or ELANE-related neutropenia (PMID: 23463630; Inviate). In at least one individual the variant was observed to be de novo. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This variant disrupts the p.Pro139 amino acid residue in ELANE. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 11001877, 14962902, 21425445, 23463630, 30040071; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
