What do I call my "X-Gene" "Weapon-X" and "Mutants" without sounding like Im ripping off the X-Men?

So I’m writing a novel surrounding a world similar to ours, but they have people who can get these mutated genes that gives them powers/mutations. The government takes advantage of these and forces some of the stronger ones to become these living, super soldier weapons. I’m currently calling it an “A-Gene” and the mutants are called “Anomalies”, while the military program is called the A-Program, and they have “Weapon A”. It just doesn’t sound good to me personally, and the letter X would make the most sense being the symbol for a variable, but it would sound like I’m straight up copying the X-Men. (Please note the plot and characters are very different, it's just these few terms.) What should I do about this?
