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.

Telangiectasia, hereditary hemorrhagic, type 1 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingARUP Laboratories, Molecular Genetics and Genomics, ARUP LaboratoriesSep 06, 2023The ENG c.1447G>A; p.Val483Ile variant (rs141330288), to our knowledge, is not reported in the medical literature but is reported as likely benign in ClinVar (Variation ID: 414304). This variant is found in the general population with an overall allele frequency of 0.02% (48/274678 alleles) in the Genome Aggregation Database, with an increased frequency of 0.1% in East Asians. The valine at codon 483 is weakly conserved, and computational analyses (SIFT, PolyPhen-2) predict that this variant is tolerated. However, given the lack of clinical and functional data, the significance of the p.Val483Ile variant is uncertain at this time. -
