X-linked hypophosphatemic rickets
: Enamel abnormalities and oral clinical findings.
Hypophosphatemia is not associated with race or gender in Caucasians except X-linked hypophosphatemic rickets
. Acquired hypophosphatemia is most commonly seen during the transition from puberty to adulthood.
FGF23 is being researched in the context of X-linked hypophosphatemic rickets
, mineral bone disorder (MBD), chronic kidney disease (CKD), tumor-induced osteomalacia and hyperphosphatemia.

Development of CPPD crystal deposition disease in young people (<55 years) may be associated with metabolic diseases such as hemochromatosis, hyperparathyroidism, hypomagnesemia, Wilson's disease, hypothyroidism, gout, acromegaly, and X-linked hypophosphatemic rickets
. Unlike in gout, there is currently no effective treatment that reduces or removes calcium pyrophosphate crystals from a joint.
The inherited causes of hypophosphatemic osteomalacia include X-linked hypophosphatemic rickets
(XLH), autosomal dominant hypophosphatemic rickets (ADHR), autosomal recessive hypophosphatemic rickets (ARHR), and hereditary hypophosphatemic rickets with hypercalciuria (HHRH) which are biochemical equivalents of TIO with high or inappropriately normal levels of FGF23 [1, 13].
The processing of DMP1 is crucial in osteogenesis and dentinogenesis, and a failure in this processing would cause defective mineralisation in bone and dentine, as observed in X-linked hypophosphatemic rickets
. Functional studies have demonstrated that DMP1 is essential in the maturation of odontoblasts and osteoblasts, as well as in mineralisation via local and systemic mechanisms [Feng et al., 2003].
