ELN

Alias

SVAS; WBS; WS

Associated disorders

The ELN gene is associated with autosomal dominant supravalvar aortic stenosis (SVAS) (MedGen UID: 2001), autosomal dominant cutis laxa (MedGen UID: 120630), and is one of the genes commonly deleted in the microdeletion associated with Williams syndrome (WS) (MedGen UID: 59799).

Invitae tests that include this gene:

The ELN gene encodes tropoelastin. Multiple copies of tropoelastin combine to form the protein elastin, which is a component of elastic fibers. These fibers give connective tissue its characteristic strength and flexibility and provide support to organs and tissues via the extracellular matrix

Assay and technical information

Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).

Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence in the transcript listed below. In addition, analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any specific limitations in the analysis of these genes are also listed in the table below.

Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
