Three genetic mutations that can give superhuman abilities

Genetic mutations already in the population today may make the X-men movies seem less like science fiction than you think. It turns out that there are some genetic mutations that seemingly give some people superhuman abilities. For example, some people have a very rare genetic mutation that makes muscle cells grow bigger and divide more than usual, resulting in a condition where people, and even children, can look like body builders. A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations can be beneficial, harmful or neutral depending on their context and location.
