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]

Significance: Uncertain risk allele
Review Status: criteria provided, single submitter
Collection Method: research

Potent mutations in TGFBR2 gene encodes the transforming growth factor that have been associated with angiogenesis and diabetic retinopathy. More clinical studies are needed for stronger association. However, more evidence is required to confer the association of this particular variant rs200111443 with diabetic retinopathy. -
