So I have Phenylketonuria. Obviously I know the whole "PAH gene doesn't work and so my body doesn't produce phenylalanine" thing but I recently discovered some paper that lists my mutations, which are "R408W" and "Y356X". What do these mean in layman's terms? Like what information does that specifically tell about a condition/how it happened? I'm super interested in this since I wanna understand why specifically I have this condition lol.
