    • Human diseases caused by dominant, gain-of-function mutations develop in heterozygotes bearing one mutant and one wild-type copy of a gene. Because the wild-type gene often performs important functions, whereas the mutant gene is toxic, any therapeutic strategy must selectively inhibit the mutant while retaining wild-type gene expression. The present invention includes methods of specifically inhibiting the expression of a mutant allele, while preserving the expression of a co-expressed wild-type allele using RNAi, a therapeutic strategy for treating genetic disorders associated with dominant, gain-of-function gene mutations. The invention also includes small interfering RNAs (siRNAs) and small hairpin RNAs (shRNAs) that selectively suppress mutant, but not wild-type, expression of copper zinc superoxide dismutase (SOD1), which causes inherited amyotrophic lateral sclerosis (ALS). The present invention further provides asymmetric siRNAs and shRNAs with enhanced efficacy and specificity and mediating RNAi.
    • 在具有一个基因的一个突变体和一个野生型拷贝的杂合子中,由显性增益功能突变引起的人类疾病发生。 因为野生型基因通常具有重要的功能,而突变基因是有毒的,任何治疗策略必须选择性地抑制突变体,同时保留野生型基因表达。 本发明包括特异性抑制突变等位基因表达的方法,同时使用RNAi保护共表达野生型等位基因的表达,用于治疗与显性功能性获得功能基因突变相关的遗传疾病的治疗策略。 本发明还包括小干扰RNA(siRNA)和小发夹RNA(shRNA),其选择性地抑制引起遗传性肌萎缩性侧索硬化(ALS)的铜锌超氧化物歧化酶(SOD1)的突变体而不是野生型表达。 本发明还提供了具有增强的功效和特异性并介导RNAi的不对称siRNA和shRNA。
