The NM_001114753.3(ENG):c.1415_1424delAGAGCTTTGT (p.Gln472ArgfsTer16) variant causes a frameshift change. The variant is predicted to lead to nonsense-mediated mRNA decay (NMD). The gene ENG is a tumor suppressor gene (CancerMine: 3 TSG, 1 driver citations). The gene ENG is a cancer driver gene (CancerMine: 3 TSG, 1 driver citations). Note: allele frequency estimates from gnomAD may be inaccurate for this variant type (MNP or indel longer than 3 bp) due to technology limitations. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. Variant has been reported in ClinVar as Pathogenic/Likely Pathogenic (★).

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.
