The spelling of "mutuant" may seem confusing, but it follows the rules of English phonetics. The word is pronounced /mjutuənt/, with the stress on the second syllable. The "u" represents the /juː/ sound, as in "mule" or "futile." The "a" represents the /ə/ schwa sound, which is unstressed and pronounced as a neutral vowel sound. The final "-ant" is pronounced /ənt/, with the stress on the final syllable. Despite its unusual spelling, "mutuant" is a valid word used to describe something that is undergoing mutation.
