After all, gene mutation in general causes genetic changes which leads at last to diseases .The three types:- substitution, deletion and insertion- are dangerous abnormal situations that could happen in the human body. Scientists all over the world are working and collaborating with each other trying to find a solution which heals people who have genetic mutation. Recently, they found out that they can make some changes in the genetic serial but it is hard for them because it requires an accurate hard work for hours and hours to do so and this is caused by the micro parts that it includes. Thus, researches and laboratorial experiments still going on to find a particular solution for the gene mutation. Hope is still a live on the hands of the scientists who can make it possible to live without genetic mutation .
