Successful Correction by Prime Editing of a Mutation in the <i>RYR1</i> Gene Responsible for a Myopathy

We report the first correction from prime editing a mutation in the <i>RYR1</i> gene, paving the way to gene therapies for RYR1-related myopathies. The <i>RYR1</i> gene codes for a calcium channel named Ryanodine receptor 1, which is expressed in skeletal muscle fibers. The f...

description We report the first correction from prime editing a mutation in the <i>RYR1</i> gene, paving the way to gene therapies for RYR1-related myopathies. The <i>RYR1</i> gene codes for a calcium channel named Ryanodine receptor 1, which is expressed in skeletal muscle fibers. The failure of this channel causes muscle weakness in patients, which leads to motor disabilities. Currently, there are no effective treatments for these diseases, which are mainly caused by point mutations. Prime editing allows for the modification of precise nucleotides in the DNA. Our results showed a 59% correction rate of the T4709M mutation in the <i>RYR1</i> gene in human myoblasts by RNA delivery of the prime editing components. It is to be noted that T4709M is recessive and, thus, persons having a heterozygous mutation are healthy. These results are the first demonstration that correcting mutations in the RYR1 gene is possible.
