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.

Johns Hopkins Genomics, Johns Hopkins University
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This ENG variant (rs147188969) is rare (<0.1%) in a large population dataset (gnomAD: 10/237498 total alleles; 0.004211%; no homozygotes). A single submitter in ClinVar classifies this variant as uncertain and p.Gln625Glu has not been reported in the literature to our knowledge. Of two bioinformatics tools queried, one predicts that the substitution would be damaging, while the other predicts that it would be benign. The glutamine residue at this position is evolutionarily conserved across some species, but not all. Due to lack of segregation and functional data, we consider the clinical significance of c.1873C>G to be uncertain at this time.

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

Variant summary: ENG c.1873C>G (p.Gln625Glu) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 4.8e-05 in 1587608 control chromosomes. The observed variant frequency is approximately 1.15 fold of the estimated maximal expected allele frequency for a pathogenic variant in ENG causing Hereditary Hemorrhagic Telangiectasia phenotype (4.2e-05). To our knowledge, no occurrence of c.1873C>G in individuals affected with Hereditary Hemorrhagic Telangiectasia and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 577031). Based on the evidence outlined above, the variant was classified as likely benign.
