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]

Familial thoracic aortic aneurysm and aortic dissection

Uncertain:1Benign:1

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Sep 24, 2022	The p.V16M variant (also known as c.46G>A), located in coding exon 1 of the TGFBR1 gene, results from a G to A substitution at nucleotide position 46. The valine at codon 16 is replaced by methionine, 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. -
