How to Pronounce REYE Apostrophe S

Ricketts disease affects bone development in children. What do you get if you take Advil as a child? No, not iboprofen. Reas. You look at that word and you tell me what that is. I'm trying to find it. It's pronounced rise syndrome. But the one I found is just REYE apostrophe S. According to first YouTube video that says the pronunciation, they pronounce it rise syndrome. Yeah, because it's got I in it.
