HPGD基因缺失突变致厚皮性骨膜病一例


【摘要】
目的通过基因测序,在分子水平确诊厚皮性骨膜病l例。方法收集1例26岁男性厚皮性骨膜
病患者及其父母外周血DNA,PCR扩增HPGD及SLC02A1基因外显子片段,通过基因测序查找有无突变。根据测 序结果进行蛋白质空间结构的同源性分析。结果基因测序结果显示,患者HPGD基因第3外显子存在移码突 变c.310 31ldelCT(p.L104AfsX3),为纯合子,其母为该突变的杂合子携带者,其父正常。蛋白空间结构预测显示,上 述基因突变可使编码蛋白缩短60%。结论厚皮性骨膜病的典型临床表现及影像学表现有助于诊断,HPGD、 SLC02A1基因突变测定则是确诊的主要方法。
