The ENST00000344849.5(ENG):c.1873C>G(p.Gln625Glu) variant causes a missense change. The variant allele was found at a frequency of 0.0000479 in 1,587,608 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/18 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. Q625Q) has been classified as Likely benign.

Submissions by phenotype
Telangiectasia, hereditary hemorrhagic, type 1 Uncertain:1
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.
not specified Benign:1
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.
