Crohns is a gigantic umbrella term for multiple phenotypes of similar disease patterns imo
Infantile crohns is vastly different than very early onset crohns and those differ from pediatric crohns .
That only makes up 10% of crohns cases
Adult crohns as well has 3-4 phenotypes which behave differently and respond differently to different types of meds
Studies on genetics and what genes cause what in crohns change every few years
At least in the past 12 years my kiddo has been dealing with it
Basically they need better subsets similar to juvenile arthritis
One umbrella term but many subtypes with different names and treatments
