Genes affected

ENG (HGNC:3349): (endoglin) This gene encodes a homodimeric transmembrane protein which is a major glycoprotein of the vascular endothelium. This protein is a component of the transforming growth factor beta receptor complex and it binds to the beta1 and beta3 peptides with high affinity. Mutations in this gene cause hereditary hemorrhagic telangiectasia, also known as Osler-Rendu-Weber syndrome 1, an autosomal dominant multisystemic vascular dysplasia. This gene may also be involved in preeclampsia and several types of cancer. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant classified as Uncertain Significance - Favor Benign. The c.1742-15G>A va riant in ENG has not been previously reported in individuals with pulmonary hype rtension, but has been identified in 8/18138 East Asian chromosomes by the Genom e Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs201678 228). This variant is located in the 3' splice region. Computational tools do no t suggest an impact to splicing. However, this information is not predictive eno ugh to rule out pathogenicity. In summary, while the clinical significance of th e c.1742-15G>A variant is uncertain, these data suggest that it is more likely t o be benign. ACMG/AMP Criteria applied: BP4 (Richards 2015). -
