Design of functional small interfering RNAs targeting amyotrophic lateral sclerosis-associated mutant alleles.

Background: RNA interference (RNAi) is a potential cure for amyotrophic lateral sclerosis (ALS) caused by dominant, gain-of-function superoxide dismutase 1 (SOD1) mutations. The success of such therapy relies on the functional small interfering RNAs (siRNAs) that can effectively deliver RNAi. This study aimed to design the functional siRNAs targeting ALS-associated mutant alleles.
