摘要
目的:检测汉族寻常型鱼鳞病(Ⅳ)丝聚合蛋白基因的突变。方法:提取65例Ⅳ患者及70例健康对照者的基因组DNA,采用MassARRAY(r)分子量阵列技术分析丝聚合蛋白基因5个突变位点(3321delA,441delA,1249 insG,E1795X和S3296X)。结果:34例(52.31%)Ⅳ患者发现丝聚合蛋白3321delA基因突变,对照组有4例(5.71%)发生该基因突变;1例(1.54%)患者发现丝聚合蛋白441delA基因突变,对照组没有发现该基因突变。患者组及对照组均未见丝聚合蛋白1249insG,E1795X及S3296X基因突变。结论:丝聚合蛋白基因突变可能与汉族人群Ⅳ易感性相关。丝聚合蛋白33-21delA基因突变可能是汉族Ⅳ主要的突变位点。
Objective: To detect filaggfin mutations in Chinese Han nationality patients with ichthyosis vulgaris (Ⅳ). Methods: Five filaggrin locus mutations (3321delA, 441delA, 1249insG, E1795X and S3296X) were detected by using the Sequenom/MassARRAY system in a cohort of 65 Chinese IV patients and in 70 control individuals. Results: Filaggrin mutation (3321delA) was found in 34(52.31% ) patients and in 4(5.71% ) healthy controls, respectively. Filaggrin mutation (441delA) was found in 1(1.54% ) patient. Filaggrin mutations (1249insG, E1795X and S3296X) were not found in these patients and controls. Conclusion: Our findings suggest that filaggrin mutations may be related with IV susceptibility in Chinese Han nationality. The filaggrin mutation (3321delA) represents the most frequent locus in Chinese IV patients.
