主 题:Perforin Mutation Lymphoma
摘 要:BACKGROUND:Perforin gene(PRF1) mutations have been reported in patients with lymphoma,but the prevalence and characteristics of PRF1 mutation have not been identified in Chinese patients with ***:Seventy-seven patients with lymphoma,including 6 patients with Hodgkin lymphoma and 71 patients with non-Hodgkin lymphoma,were *** samples from peripheral blood were used for PRF1 mutation detection by the PCR-sequencing ***:Eleven novel PRF1 mutations were found in 8 of the 77 patients with *** or compound monoallelic missense mutations in 3 patients indicated the severe impairment of perforin function,monoallelic missense mutations in 3 patients possibly contributed a genetic predisposition to malignancies,and synonymous mutations in 2 patients showed unknown ***:The frequency of EBV infection was similar in lymphoma patients with PRF1 mutations and those without the *** same PRF1 mutations were also found in DNA samples from nails or hair follicles from 4 patients with PRF1 mutations,suggesting that these mutations may be of germ-line origin.
