Variant summary
Our verdict is Uncertain significance. Variant got 4 ACMG points: 5P and 1B. PM1PM2PP2BP4
The NM_004612.4(TGFBR1):c.1415G>A(p.Arg472Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000685 in 1,460,884 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. R472R) has been classified as Likely benign.

Familial thoracic aortic aneurysm and aortic dissection Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jun 19, 2017 | This sequence change replaces arginine with lysine at codon 472 of the TGFBR1 protein (p.Arg472Lys). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and lysine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with a TGFBR1-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, this variant has uncertain impact on TGFBR1 function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
