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.

Supravalvar aortic stenosis Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Mar 02, 2012 | The 890-2A>G variant (ELN) has not been reported in the literature nor previousl y identified by our laboratory. This variant occurs in the invariant region (+/- 1, 2) of the splice consensus sequence and is predicted to cause altered splici ng leading to an abnormal or absent protein. Loss of function of the ELN gene is an established mechanism of disease in SVAS (Human Gene Mutation Database, HGMD ). In summary, the 890-2A>G variant meets out pathogenicity criteria (http://pcp gm.partners.org/lmm). - |
