X-linked hypophosphatemic rickets (PHEX mutation): A case report and literature review.

چکیده
Hypophosphatemic rickets is a rare form of rickets that affect children. The diagnosis requires high index of suspicion. We report a case of Hypophosphatemic rickets in 18-month-old Saudi boy presented with delayed walking and lower limb deformity. The diagnosis was confirmed by bone profile, radiological study and genetic testing, which reveled PHEX mutation. The patient was successfully treated by phosphate supplement.

Genetic Testing Confirmed the Early Diagnosis of X-Linked Hypophosphatemic Rickets in a 7-Month-Old Infant.
Loss-of-function mutations in the phosphate regulating gene with homologies to endopeptidases on the X-chromosome (PHEX) have been causally associated with X-linked hypophosphatemic rickets (XLHR). The early diagnosis of XLHR in infants is challenging when it is based solely on clinical features and biochemical findings. We report a 7-month-old boy with a family history of hypophosphatemic rick...

INTRODUCTION X-linked hypophosphatemic rickets (XLHR) is a dominant inherited disease caused by isolated renal phosphate wasting and impairment of vitamin D activation. We present a girl with X-linked hypophosphatemic rickets (XLHR) as a consequence of de novo mutation in the PHEX gene. CASE OUTLINE A 2.2-year-old girl presented with prominent lower limb rachitic deformity, waddling gait and ...
متن کاملA Novel PHEX Mutation in Japanese Patients with X-Linked Hypophosphatemic Rickets
X-linked hypophosphatemic rickets (XLH) is a dominant inherited disorder characterized by renal phosphate wasting, aberrant vitamin D metabolism, and abnormal bone mineralization. Inactivating mutations in the gene encoding phosphate-regulating gene with homologies to endopeptidases on the X chromosome (PHEX) have been found to be associated with XLH. Here, we report a 16-year-old female patien...

X-linked dominant hypophosphatemic rickets (XLH) is the most prevalent genetic form of hypophosphatemic rickets. Standard treatment of XLH patients includes long-term administration of phosphate and calcitriol. Treated patients usually respond well to the conventional therapy and demonstrate amelioration of rachitic symptoms and improved growth. However, long-term administration of phosphate an...
متن کاملHypophosphatemic Rickets in Siblings: A Rare Case Report
Hypophosphatemic rickets (HR) is a type of hereditary rickets characterized by persistent hypophosphatemia and hyperphosphaturia. The most predominant type is inherited in an X-linked fashion and caused by mutation in the gene encoding the phosphate-regulating endopeptidase homolog, X-linked (PHEX), identified in 1995. The X-linked hypophosphatemic (XLH) rickets is a rare hereditary metabolic d...
