The majority of embryos
developed unintended mutations, and only a small fraction of them had the blood - disorder gene correctly modified — not what you'd call a success.
As CRISPR - Cas9 starts to move into clinical trials, a new study published in Nature Methods has found that the gene - editing technology can introduce hundreds
of unintended mutations into the genome.

Though gene - editing tools have the power to potentially cure a number of diseases, scientists have proceeded cautiously, in part to avoid
introducing unintended mutations into the germ line (cells that become eggs or sperm).
Traditionally, these processes can force selective pressures that
favor unintended mutations to the karyotype, conferring competitive advantages to in vitro growth.
A recent study claiming CRISPR gene - editing can
cause unintended mutations has sent shockwaves through the scientific community.
The IBS Center for Genome Editing published two studies at once in Nature Biotechnology, showing Cpf1's superiority as a precise genome editing tool with
no unintended mutations.
KIM Jin - soo, Director of the IBS Center for Genome Editing and corresponding author of the two studies commented, «Since the two studies have proved the superior specificity of Cpf1, this new nuclease will be more widely used for precise genome editing that does not produce
any unintended mutations.
The technique also introduced new,
unintended mutations.
New way of using CRISPR to edit defective heart gene seems to overcome problems of
unintended mutations and incomplete repair
Even embryos that contained the intended HIV - blocking mutation in one copy of CCR5 either had normal DNA or
an unintended mutation in other copies of the gene.
The team who previously stated that CRISPR caused hundreds of
unintended mutations are unable to replicate their controversial result.
