BACKGROUND: @entity715 ( @entity715 ) is a typical manifestation of @entity11998 vera (PV) or essential thrombocythaemia (ET). The recently discovered JAK2V617F somatic mutation is closely associated with @entity102 ( @entity102 ). We investigated whether @entity715 involving the inferior vena cava (IVC) is also related to the JAK2V617F mutation or @entity102 . METHODS: Blood samples were obtained from 40 IVC @entity715 @entity1 . Fifty-three @entity1 with isolated @entity1150 ( @entity1150 ) and 20 @entity715 @entity1 served as controls. The presence of the JAK2V617F mutation was assessed by real-time polymerase chain reaction (RT-PCR). RESULTS: The JAK2V617F allele was not detected in any of the IVC @entity715 @entity1 but was detected in one @entity1 (2%) with isolated @entity1150 . However, the mutation-carrying @entity1 did not exhibit symptoms of @entity102 . Even after an observation period of 30months, the @entity1 's complete blood cell count did not exhibit any pathology. In contrast, the JAK2V617F allele was detected in four @entity1 with @entity715 (20%) and @entity102 . CONCLUSION: According to our data, there is no evidence that IVC @entity715 is associated with the JAK2V617F mutation or the presence of @entity102 .
