Novel Association of a Familial TGFBR1 Mutation in Loeys-Dietz Syndrome with Concomitant Hematologic Malignancy.

Novel Association of a Familial TGFBR1 Mutation in Loeys-Dietz Syndrome with Concomitant Hematologic Malignancy. Korean J Thorac Cardiovasc Surg. 2019 Oct;52(5):376-379 Authors: Disha K, Schulz S, Breuer M, Owais T, Girdauskas E, Kuntze T Abstract Concomitant Loeys-Dietz syndrome (LDS) and hematologic malignancies are exceptionally rare. This is the first report of a patient operated on for aortic root dilation who had been previously diagnosed with LDS and B-cell-lymphoma. After completion of chemotherapy and complete remission, an elective valve-sparing aortic root replacement (using the David-V method) was performed. Due to the positive family history, pre-operative genetic counseling was conducted, and revealed LDS with a TGFBR1 (transforming growth factor beta receptor type I) mutation in 6 probands of the family, albeit in 1 of them posthumously. This missense mutation has been previously described in relation to aortic dissection, but a causative relationship to malignancy has so far neither been proposed nor proven. PMID: 31624717 [PubMed]
