Numerous hereditary stone conditions lead to NL and/or NC, such as cystinuria, distal renal tubular acidosis (dRTA), Dent disease, familial hypomagnesaemia with hypercalciuria and nephrocalcinosis (FHHNC), infantile hypercalcemia type 1 (HCINF1), and primary hyperoxaluria type 1 (PH1) [14,15,16,17,18,19]. This evidence concerns the gene CYP24A1 and primary hyperoxaluria type 1.
