Question Vit D dependent versus Vit D resistant Rickets!

so guys, is vit D resistant kidneys and vit d dependant kidneys are the same thing?
I know that there r 2 types of vit d dependent kidneys.. type 1, in which there is inc PTH, dec ca and p and 1,25 cholicalciferol but normal 25 cholicalciferol cuz of deficiency of 1 alpha hydrxylase..
type 2 has inc 1,25 cholicaciferol, inc pth but dec ca and p.

so is vit d resistent kidneys just as the same thing as type 2 as i mentioned above cuz as the name says, vit d resistent, means there will be inc vit d but since kidneys are resistent and it will cause dec in ca and p which wil inc in pth!
it sounds like VIT D RESISTENT KIDNEYS AND VIT D dependent type 2 the same things,,
can anyone explain

Vit D dependent: There will be deficiency in 5hydroxy alpha hydroxylase. so 25 hydroxyvitd elevated. On supplementing with 1,25 hydroxyvitd changes can be seen.


vit D resistent: There will be defect in tubular reabsorption of phosphate. Due to point mutation of vit d receptor, increased serum 1,25 dihydroxyvit d. No changes on supplemental with vit d.


Yes biochemical changes in both are same.
