Variant summary
Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1PM2PM5PP2PP3_Strong
The NM_004612.4(TGFBR1):c.734A>C(p.Glu245Ala) 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. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E245G) has been classified as Pathogenic.

Genes affected
TGFBR1 (HGNC:11772): (transforming growth factor beta receptor 1) The protein encoded by this gene forms a heteromeric complex with type II TGF-beta receptors when bound to TGF-beta, transducing the TGF-beta signal from the cell surface to the cytoplasm. The encoded protein is a serine/threonine protein kinase. Mutations in this gene have been associated with Loeys-Dietz aortic aneurysm syndrome (LDAS). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]

ACMG classification
Classification made for transcript
Verdict is Pathogenic. Variant got 11 ACMG points.
PM1
In a helix (size 10) in uniprot entity TGFR1_HUMAN there are 4 pathogenic changes around while only 0 benign (100%) in NM_004612.4
PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr9-99138018-A-G is described in Lovd as [Pathogenic].
PP2
Missense variant in the TGFBR1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 48 curated pathogenic missense variants (we use a threshold of 10). The gene has 16 curated benign missense variants. Gene score misZ: 2.7935 (below the threshold of 3.09). Trascript score misZ: 3.6468 (above the threshold of 3.09). GenCC associations: The gene is linked to familial thoracic aortic aneurysm and aortic dissection, Loeys-Dietz syndrome, multiple self-healing squamous epithelioma, Loeys-Dietz syndrome 1.
