Summary
It has been suggested that an impaired thrombomodulin (TM) function could constitute an abnormality leading to thromboembolic disease (TED). The TM gene from 51 unrelated American patients with TED and 100 American blood donors was screened for mutations. Four heterozygous point mutations in the TM gene were detected. The mutations are distributed throughout the TM gene and predict amino acid changes 1) Pro483 to Leu, 2) Gly61 to Ala, 3) Asp468 to Tyr (earlier described) and 4) a silent mutation not predicting any amino acid change at Glu163. Family studies reveal that the occurrence of the different TM mutations is associated with a history of TED, but there are indications of multiple risk factors and no perfect co-segregation of the TM defects and TED. Among the controls, three individuals carried heterozygous TM variants predicting either a Pro477-Ser mutation (two cases) or an Asp468-Tyr mutation. Our results thus demonstrate that a previously undocumented abnormality in the protein C anticoagulant pathway, a defect in the TM gene, to a certain extent co-segregates with familial thrombophilia. Further studies are needed to prove the causality of these TM mutations.
