Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000501.4(ELN):c.862dup(p.Ala288GlyfsTer25) variant causes a frameshift change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. P286P) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Genes affected
ELN (HGNC:3327): (elastin) This gene encodes a protein that is one of the two components of elastic fibers. Elastic fibers comprise part of the extracellular matrix and confer elasticity to organs and tissues including the heart, skin, lungs, ligaments, and blood vessels. The encoded protein is rich in hydrophobic amino acids such as glycine and proline, which form mobile hydrophobic regions bounded by crosslinks between lysine residues. Degradation products of the encoded protein, known as elastin-derived peptides or elastokines, bind the elastin receptor complex and other receptors and stimulate migration and proliferation of monocytes and skin fibroblasts. Elastokines can also contribute to cancer progression. Deletions and mutations in this gene are associated with supravalvular aortic stenosis (SVAS) and autosomal dominant cutis laxa.

Submissions by phenotype
not provided Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Jun 25, 2014 | The c.862dupG mutation in the ELN gene causes a frameshift starting with codon Alanine 288, changes this amino acid to a Glycine residue and creates a premature Stop codon at position 25 of the new reading frame, denoted p.Ala288GlyfsX25. This mutation is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. This mutation has not been previously reported to our knowledge. This variant was found in ELN - |
Supravalvar aortic stenosis Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Aug 07, 2012 | The Ala288fs variant in ELN has not been previously reported in the literature n or previously identified by our laboratory. This frameshift variant is predicted to alter the protein?s amino acid sequence beginning at position 288 and lead t o a premature termination codon 25 amino acids downstream. This alteration is th en predicted to lead to a truncated or absent protein. Loss of function of the ELN gene is an established mechanism of disease in SVAS (Human Gene Mutation Dat abase, HGMD). In summary, the Ala288fs variant meets our criteria for pathogenic ity (http://pcpgm.partners.org/lmm). - |
