TheX-Men have already been confirmed to appear in the Marvel Cinematic Universe, but the MCU still needs to avoid an X-Men problem of its own creation. To date, civilians in the MCU have been exposed to superhumans, alien races, sentient robots, and Gods. In fact, they've been exposed to these events so frequently that it's become their new normal, so the addition of Mutants creates some crucial problems for the MCU — which many pre-existing X-Men theories do not consider.
The primary theme that underlies the X-Men has always been racial conflict, with Stan Lee's mutants serving as a metaphor for the Civil Rights movement. In Marvel comics, the X-Men have primarily been oppressed by humans for their gifts. Mutants are born with their powers, whereas superheroes usually go through origin stories to "earn" them in Marvel comics, creating a major difference between Mutants and superheroes. Furthermore, the conflict between the two prominent X-Men figureheads, Charles Xavier and Magneto, only exists because of how Marvel comics' society treats Mutants. Given how superheroes are currently revered in the MCU, it makes it hard to see how this conflict will translate over from the original FOX X-Men installments, as it's less likely that Mutants will be discriminated against in the MCU's current incarnation.
