Alternatively, other studies found that ALPL, CYP17, IGF2, EGFR, IL1B, IL6, ITPKC, MTNR1A, OPN, ODC, osteocalcin, RGS14, SAT1, TNFA, TRPV5, and matrix Gla protein gene polymorphisms were not associated with kidney stone recurrence [9, 34, 38–43, 46, 47, 49, 50]. Here, TRPV5 is linked to nephrolithiasis.
