SLC34A1 and rickets: The bones of these mice show a rickets-like phenotype, including a smaller size, hypomineralization, wider and unmineralized growth plates (as in rickets), severe osteomalacia, increased but hypomineralized trabecular volume, higher cortical bone volume due to unmineralized osteoid and diminished bone resorption with low osteoclast numbers, as well as lower NPT2 at renal proximal tubule epithelial cells.
