Everyone is technically in possession of genetic mutations but in layman's terms and to account for the results of the experiments conducted on him and the onset of his abilities, yes. I believe that is the case with Kilgrave. He appeared to possess a very strong persuasion ability - upon cross-examining profiles of other mutants with similar abilities, telepathic abilities, abilities which grant control of the mind, the commonalities are substantial. I can also provide a snapshot of my comparisons.
And I would be glad to take the stand to testify, if this is what is required of me.
