Genes affected
EMILIN1 (HGNC:19880): (elastin microfibril interfacer 1) This gene encodes an extracellular matrix glycoprotein that is characterized by an N-terminal microfibril interface domain, a coiled-coiled alpha-helical domain, a collagenous domain and a C-terminal globular C1q domain. The encoded protein associates with elastic fibers at the interface between elastin and microfibrils and may play a role in the development of elastic tissues including large blood vessels, dermis, heart and lung.

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpFeb 09, 2023This sequence change creates a premature translational stop signal (p.Ser40Argfs*34) in the EMILIN1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EMILIN1 are known to be pathogenic (PMID: 36351433). This variant is present in population databases (rs758895857, gnomAD 0.002%). This premature translational stop signal has been observed in individual(s) with EMILIN1-related conditions (PMID: 36351433). ClinVar contains an entry for this variant (Variation ID: 1344492). For these reasons, this variant has been classified as Pathogenic. -
