SLC34A3 and hereditary hypophosphatemic rickets with hypercalciuria: These disorders include some forms of hypophosphatemic rickets due to mutations in SLC34A3 encoding for NaPi2C (hypophosphatemic rickets with hypercalciuria, HHRH), SLC34A1 gene encoding for NaPi2a (nephrolithiasis/osteoporosis, hypophosphatemic 1, NPHLOP1), or mutation in NHERF1 gene (nephrolithiasis/osteoporosis, hypophosphatemic, 2) (19, 20).
