Özet

Mutation screening studies related with thrombosis revealed that prothrombin 20210A allele of the prothrombin gene leads to an increase in plasma prothrombin levels. The G20210A mutation screening has become a routine analysis in patients with thrombosis. For the detection of the mutation, several molecular techniques have been defined. Real-time polymerase chain reaction is an easy and feasible way to monitor this mutation according to the melting point analysis. Here we report a different pattern in the LightCycler melting point analysis of 2 patients with thrombosis. DNA sequencing of the prothrombin gene showed that these patients with an atypical melting point profile carry a 20209 C>T mutation along with a novel homozygous polymorphism at the 3′ downstream region, +4 C>T. © 2006 Carden Jennings Publishing Co., Ltd.
