CRISPR-Cas: The molecular scissors for genetic disease surgeries?

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is an emerging biomedical tool, which allows researchers to manipulate DNA sequence(s) for desired gene(s) function. Genetic disorders, namely sickle-cell anaemia and β-thalassemia, had corrected in the stem cells using CRISPR. Therefore, researchers are much optimistic that CRISPR can prevent and cure human diseases in the coming future. However, it is a debatable question that whether this tool is safe and effective for use in human.
