In
one of her videos she explained that she has a less severe case than typical because she has a compound heterozygous mutation (typical cases are some form of homozygous mutatiion I guess?). And she apparently is going to be part of a research study spanning a decade. The information is within the first several minutes of the video.
I've always thought of Cheyanne as one of the munchies who is legitimately sick but also happens to be a drama queen who got used to making sickness into her identity. She's spoken about having to be in the hospital for long periods of time as a child, that probably would leave some sort of mark of it being part of who she is. Getting a bunch of positive attention for it probably doesn't help either.
TLDR: She's not full of shit, just shitty.
