Children with rickets in these countries have shown similar blood biochemical profiles with elevated 1,25-dihydroxyvitamin D (1,25(OH)2D), parathyroid hormone (PTH) and total alkaline phosphatase (TALP) coupled with low plasma phosphate (P), normal to low plasma calcium (Ca) and a low dietary calcium intake [2–4]. This evidence concerns the gene PTH and rickets.
