seagullIt looks like it was a type II RTA. The difference is incredibly subtle from the info given in this question. +14
gonyyongHe has Fanconi syndrome which is generalized reabsorption defect in PCT which leads to metabolic acidosis and hypophosphatemia โ can lead to rickets
Also, does lead to type II RTA+17
duat98Also the proximal tubule is the place with the highest phosphate absorption rate. That's why PTH works here mostly and a little bit in the distal tubule.+6
boostcap23Another easy way to go about this one is the question tells you he has metabolic acidosis, the only that can happen with is Fanconi/Type2 RTA. The rest will cause hypokalemia and metabolic ALKALOSIS. (pg 586 FA)
Personally thought if they were going for Fanconi syndrome they would describe a lot more symptoms for the kid like growth failure or hypophosphatemic rickets but its NBME so.+2

Increased Phosphate loss --> Fanconi syndrome --> affects the PCT
