<p>To investigate the prevalence of FV Hong Kong(p.Arg306Gly) variant in patients with thrombotic disorders in South China, and to explore the association between FV Hong Kong and thrombosis according to genotype and clinical manifestations of the patients. A total of 367 patients with thrombotic disorders and 555 healthy volunteers in South China were screened by exon sequencing to identify FV Hong Kong variant carriers.

摘要

To investigate the prevalence of FV Hong Kong(p.Arg306Gly) variant in patients with thrombotic disorders in South China, and to explore the association between FV Hong Kong and thrombosis according to genotype and clinical manifestations of the patients. A total of 367 patients with thrombotic disorders and 555 healthy volunteers in South China were screened by exon sequencing to identify FV Hong Kong variant carriers. Acquired risk factors for thrombosis of all subjects were also recorded. Among 367 thrombosis patients, 10 (2.72%) carried heterozygous FV Hong Kong mutations. In contrast, 9 of 555 healthy controls (1.62%) harbored the heterozygous mutation. There is no significant differences in the prevalence rate between patients and healthy controls. Among patients with the FV Hong Kong mutation, 90% exhibited concurrent predisposing factors. The FV Hong Kong variant demonstrates a high prevalence in the South Chinese population, with a similar rate in thrombosis patients and healthy population. The variant, when co-occurring with genetic or acquired risk factors, may synergistically elevate thrombotic risk. Further investigations are warranted to elucidate the clinical implications in thrombotic disorders.
