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]

Collection Method: clinical testing

Variant summary: The TGFBR2 c.1657T>A (p.Ser553Thr) variant involves the alteration of a conserved nucleotide and 3/5 in silico tools predict a damaging outcome. This variant was found in 170/121354 control chromosomes (2 homozygotes) at a frequency of 0.0014009, which is approximately 1121 times the estimated maximal expected allele frequency of a pathogenic TGFBR2 variant (0.0000013), suggesting this variant is likely a benign polymorphism. Multiple publications have cited the variant in affected individuals. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant with conflicting classifications "uncertain significance" or "likely benign." However, it needs to be noted that many databases/clinical diagnostic laboratories that classified the variant as "uncertain significance" were performed before ExAC data was availalbe. In addition, ClinVar-Partners does state that the variant did not segregate with disease in one family. Therefore, taking all available lines of evidence into consideration, the variant of interest has been classified as Benign. -

Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
