A paper published in the journal Nature on the 2nd August described how a gene editing tool CRISPR could be used to correct a genetic mutation that leads to a heart condition. This team had performed the genetic editing on the gene sequences in dozens of viable human embryos to attempt to prevent a genetic heart condition called hypertrophic cardiomyopathy. Reproductive biologists at the Oregon Health Sciences Center in Portland, unlike all their predecessors who used this tool for genetic editing, had shown that this technique had a high success rate at correcting a disease-causing mutation in a gene. The authors of the paper claimed that CRISPR-Cas9 genome editing tool could successfully replace
