There is lots of debate on this matter since last few years. It has been made available in US, but not on large scale or on commercial purpose. But it has been kept under observation to analyse its gravity in giving results or in the detection of acute conditions in human.
Yet, these procedures are not allowed in India, as it needs lots of regulations and control procedures. And that is not organized in India on strict grounds. Our government should implement some regulatory acts and pass the same to academic institutions, government hospitals and research institutions, who are studying genomics and trying to know the depth of the mutations in personals.
I support, that if government will allow and keep an eye on the procedure, this will help us in treating and finding out the real time treatments on individual basis. Government should give green flag for safe clinical trials to be conducted to evaluate this in India.
