RCV000780771 | SCV000918304 | uncertain significance | not specified | 2018-04-30 | criteria provided, single submitter | clinical testing | Variant summary: TGFBR1 c.503G>A (p.Arg168His) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 8.2e-06 in 121350 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.503G>A in individuals affected with Aortopathy and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance. |

Ambry Genetics | RCV001873189 | SCV002641835 | uncertain significance | Familial thoracic aortic aneurysm and aortic dissection | 2021-12-16 | criteria provided, single submitter | clinical testing | The p.R168H variant (also known as c.503G>A), located in coding exon 3 of the TGFBR1 gene, results from a G to A substitution at nucleotide position 503. The arginine at codon 168 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
