GeneDx RCV000199130 SCV000250923 uncertain significance not provided 2014-02-16 criteria provided, single submitter clinical testing The T99I variant in the TGFBR2 gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. T99I results in a semi-conservative amino acid substitution of a polar Threonine residue with a non-polar Isoleucine residue at a position that is conserved across species. A mutation affecting a nearby residue (T96I) has been reported in association with Marfan syndrome type II, further supporting the functional importance of this region of the protein. The T99I variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. With the clinical and molecular information available at this time, we cannot definitively determine if T99I is a disease-causing mutation or a rare benign variant. This variant was found in TAAD
