2、对临床诊治提供参考依据。方法:连续收集10例HCM患者血液与临床资料。提取全血基因组DNA、文库制备,靶向富集8个编码肌小节蛋白的HCM的致病基因,并行高通量测序。结果:l0例患者[平均年龄为(46±7.9)岁,女性占50%]中,4例患者发现5个基因突变位点。双突变(TNNT2R286H和MYH7R663H)携带者具有HCM家族史,发病早,左心室重度肥厚,心电图呈现传导阻滞。MYBPC3D770N和MYBPC3$236G突变携带者发病年龄晚,左心室肥厚程度较轻。MYH7R869C突变携带者年龄大,左心室肥厚程度较重
3、,心电图呈现明显左心室肥大证据。结论:对10例HCM患者利用目标基因捕获测序技术筛选出5个致病突变。携带不同突变的患者其临床表型不一致,这对患者的预后和治疗提供了有利的依据。[关键词]肥厚型心肌病;突变;目标捕获;高通量测序[中图分类号]R54[文献标志码]A[文章编号]1007.5062(2014)04-599-05Theresearchofidentificationofpathogenicmutationsassociated、】Irithhypertrophiccardiomyopathybytargete
