The story is really touching and inspiring. It must be tough though, there are still bright things there waiting for you to explore! Best wishes to both!
Palovarotene is used to treat a certain rare genetic problem (fibrodysplasia ossificans progressiva-FOP). It works by reducing bone formation in muscles and tendons that can be caused by FOP. Palovarotene belongs to a class of drugs known as retinoids, which are related to vitamin A.
FOP is a super rare disease. It wouldn’t show on the typical genetic tests unless it’s specified. Stop pretending you are an expert or a smart person when you know nothing at all.
