The researchers, led by Wyss Institute Core Faculty members George Church and James Collins, developed an in vivo mutation prevention method that enables the DNA - cleaving Cas9 enzyme to discriminate between genomic target sites differing by a single nucleotide and to exclusively cut the unwanted one.

Silent mutations occur when the change of a single DNA nucleotide within a protein - coding portion of a gene does not affect the sequence of amino acids that make up the gene's protein.

During genome evolution the spectrum of possible mutations is extremely broad, ranging from single nucleotide substitutions all the way up to Mb - sized rearrangements and translocations.

The researchers zeroed in on a single - nucleotide polymorphism (SNP) that appeared to be the causal mutation, typically consisting of an adenine nucleotide but appearing as a guanine nucleotide in roughly a third of the population, located in a region of noncoding DNA that falls within the PHACTR1 gene.
