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]

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

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. -

TGFBR1 NM_004612.3 exon 3 p.Val153Ile (c.457G>A): This variant has been reported in the literature in one individual with vascular anomalies (Mattassi 2018 PMID:28655553). However, this variant is present in 0.1% (129/64576) of European alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/9-99132622-G-A?dataset=gnomad_r3) and is present in ClinVar, with several labs classifying this variant as benign or likely benign (Variation ID:213868). Evolutionary conservation and computational predictive tools suggest that this variant may not impact the protein. In summary, data on this variant suggests that this variant does not cause disease, but requires further evidence. Therefore this variant is classified as likely benign. -
