Variant summary
Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM1PM2PM5PP3PP5_Moderate
The NM_003242.6(TGFBR2):c.1576G>A(p.Glu526Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E526Q) has been classified as Pathogenic.

Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | May 08, 2021 | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.Glu526 amino acid residue in TGFBR2. Other variant(s) that disrupt this residue have been determined to be pathogenic (Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt TGFBR2 protein function. This variant has not been reported in the literature in individuals with TGFBR2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamic acid with lysine at codon 526 of the TGFBR2 protein (p.Glu526Lys). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and lysine. - |
