Yeah, the CCVI angle is interesting. From what I understand from the conference Cheer attended, people are born with stenosis, but that isn't to say that it has to be entirely about the genes. Could it not be due to "environmental factors" in the womb? Or even something simplistic like the position of the foetus? It's all just pie in the sky speculation anyway. It will take years of thorough research to get to the bottom of this and the answer isn't going to come from TIMS.
