8th HD Therapeutics Conference
第八届亨廷顿舞蹈病(HD)治疗会议
A forum for drug discovery &
development
药物研发研讨会
亨廷顿舞蹈病(Huntington disease,
HD)是一种罕见的常染色体显性遗传神经退行性疾病,临床表现为不自主舞蹈样动作、精神行为异常和认知障碍。在白种人群患病率约为5-10/10万。HD致病基因编码huntingtin(htt)蛋白,在第一个外显子中存在一段多态的CAG重复序列,编码多聚谷氨酰胺链,正常范围为6-26次,异常范围大于36次,携带36-39次重复的个体可表现为外显不全或者延迟外显。异常重复序列存在逐代扩展趋势,引起遗传早现。几种神经退行性疾病与HD致病基因突变形式相似,基因编码区CAG重复扩展引起蛋白中多聚谷氨酰胺链延长致病,统称为多聚谷氨酰胺疾病(polyglutamine
disease,polyQ),包括脊髓小脑共济失调SCA1、SCA2、SCA3、SCA6、SCA7、SCA17和DRPLA,以及延脊肌萎缩症(SBMA)。作为polyQ疾病的代表,HD发病机制研究和治疗探索对于其他类型疾病具有重要的参考意义。
