The Strucker twins are somewhat special, I think to recall they were Homo superior but that the experiments revealed them.

For Sinister, I haven't followed, but he has been considered a mutant from time to time, possibly because he was allegedly powered by (others') X-Genes.

If they are stated to be mutants, I think we can accept them. But only "if".
