Key result
Mutant-specific siRNAs targeting the COL6A1 c.850G>A mutation potently and selectively blocked expression of mutant collagen VI and allowed normal extracellular localization in UCMD fibroblasts.
Why the study?
Does allele-specific siRNA knockdown of mutant COL6A1 mRNA restore cellular function in UCMD fibroblasts?
Does allele-specific siRNA knockdown of mutant COL6A1 mRNA restore cellular function in UCMD fibroblasts?
Allele-specific siRNA knockdown of mutant COL6A1 mRNA restores normal collagen VI localization in UCMD fibroblasts, suggesting a potential therapeutic approach.

Supports allele-specific siRNA development for UCMD; leaves open in vivo efficacy and clinical translation.
Noguchi et al. (2014) studied Ullrich congenital muscular dystrophy (UCMD). Mutant-specific siRNAs targeting COL6A1 c.850G>A (p.G284R) mutation was evaluated on Extracellular localization of collagen VI and expression of mutant collagen VI. Mutant-specific siRNAs targeting the COL6A1 c.850G>A mutation potently and selectively blocked expression of mutant collagen VI and allowed normal extracellular localization in UCMD fibroblasts.
