Autosomal dominant hypophosphatemic rickets is linked to chromosome 12p13.

Hereditary hypophosphatemic rickets

Hereditary hypophosphatemic rickets (HHR) are a group of diseases characterized by renal phosphate wasting causing growth retardation, rickets and osteomalacia. The most common form is the X-linked dominant hypophosphatemic rickets caused by inactivating mutations in the PHEX gene. The other hereditary hypophosphatemic syndromes present a lower prevalence. These include autosomal dominant hypop...

Familial Hypophosphatemic Rickets - A Case Report and Review of Literature

Introduction Familial hypophosphatemic or X-linked hypophosphatemic (XLH) rickets is the most common form of non-nutritional rickets1. The prevalence of XLH rickets yet remain unknown in Bangladesh. It is an Xlinked dominant disorder characterized by renal phosphate wasting with consequent defect of bone mineralization1. Some form of the disease are observed to be transmitted which followed an ...

Molecular Bases of Diseases Characterized by Hypophosphatemia and Phosphaturia: New Understanding

Serum phosphate levels are regulated in both calcium-dependent and -independent fashions. Active vitamin D increases while PTH decreases serum phosphate levels in association with the elevation of serum calcium. On the other hand, a calcium-independent phosphaturic factor, historically called phosphatonin is believed to exert a physiological function based on findings in hereditary and tumor-in...

Characterization of native FGF23 protein and mutant forms causing autosomal dominant hypophosphatemic rickets and familial tumoral calcinosis

Autosomal-recessive hypophosphatemic rickets is associated with an inactivation mutation in the ENPP1 gene.

Human disorders of phosphate (Pi) handling and hypophosphatemic rickets have been shown to result from mutations in PHEX, FGF23, and DMP1, presenting as X-linked recessive, autosomal-dominant, and autosomal-recessive patterns, respectively. We present the identification of an inactivating mutation in the ecto-nucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) gene causing autosomal-recessiv...
