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.
