Genes affected
TGFBR2 (HGNC:11773): (transforming growth factor beta receptor 2) The protein encoded by this gene is a transmembrane protein that has a protein kinase domain, forms a heterodimeric complex with TGF-beta receptor type-1, and binds TGF-beta. This receptor/ligand complex phosphorylates proteins, which then enter the nucleus and regulate the transcription of genes related to cell proliferation, cell cycle arrest, wound healing, immunosuppression, and tumorigenesis. Mutations in this gene have been associated with Marfan Syndrome, Loeys-Deitz Aortic Aneurysm Syndrome, and the development of various types of tumors. Alternatively spliced transcript variants encoding different isoforms have been characterized. [provided by RefSeq, Aug 2017]

Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Jun 03, 2011 | The Pro473Gln variant has not been reported in the literature nor previously ide ntified by our laboratory. Proline (Pro) at amino acid position 473 is highly co nserved across evolutionarily distant species, increasing the likelihood that th e change is pathogenic. However, computational analyses are mixed with PolyPhen2 predicting pathogenicity, while SIFT and AlignGVGD predict this variant would b e benign. These tools have not been validated sufficiently to determine pathogen icity. Additional data is required to fully assess this variant. Therefore, the clinical significance of the Pro473Gln variant cannot be determined at this time . - |
