Personalized allele-specific CRISPR-Cas9 strategies for myofibrillar myopathy 6.

ABSTRACT: Myofibrillar myopathy 6 (MFM6) is a rare childhood-onset myopathy characterized by myofibrillar disintegration, muscle weakness, and cardiomyopathy. The genetic cause of MFM6 is p.Pro209Leu mutation (rs121918312-T) in the BAG3 gene, which generates the disease outcomes in a dominant fashion. Since the consequences of the BAG3 mutation are strong and rapidly progressing, most MFM6 patients are due to de novo mutation. There are no effective treatments for MFM6 despite its well-known genetic cause. Given p.Pro209Leu mutation is dominant, regenerative medicine approaches employing orthologous stem cells in which mutant BAG3 is inactivated offer a promising avenue. Here, we developed personalized allele-specific CRISPR-Cas9 strategies capitalizing on PAM-altering SN
