    [Disorders Caused by Mutations in Calcium-Sensing Receptor and Related Diseases.]
    Clin Calcium 2017 ;27(4):521-527
    Disorders Caused by Mutations in Calcium-Sensing Receptor and Related Diseases.
    Sensing of extracellular calcium(Ca2+)levels involves the Ca-sensing receptor(CaSR), its downstream signaling molecule Gα11, and the adaptor-related protein complex 2(AP2)that plays a role in clathrin-dependent endocytosis of CaSR. Inactivating mutations in CaSR cause familial hypocalciuric hypercalcemia type 1(FHH1)and neonatal severe hyperparathyroidism(NSHPT), while activating mutations lead to autosomal dominant hypocalcemia type 1(ADH1)and Bartter syndrome type Ⅴ. Recent studies have identified that inactivating mutations in Gα11 and σ-subunit of AP2(AP2σ)also cause FHH, and these conditions have been classified as FHH2 and FHH3, respectively. Read More

Skeletal survey is the preferred initial imaging modality due to its availability and low cost. Read More

    Improved Screening Test for Idiopathic Infantile Hypercalcemia Confirms Residual Levels of Serum 24,25-(OH)2 D3 in Affected Patients.
    J Bone Miner Res 2017 Mar 17. Epub 2017 Mar 17.
    Department of Biomedical & Molecular Sciences, Queen's University, Kingston, ON, Canada.
    CYP24A1 mutations are now accepted as a cause of idiopathic infantile hypercalcemia (IIH). A rapid liquid-chromatography tandem mass spectrometry (LC-MS/MS)-based blood test enabling measurement of the 25-OH-D3 :24,25-(OH)2 D3 ratio (R) can identify IIH patients on the basis of reduced C24-hydroxylation of 25-OH-D3 by CYP24A1 in vivo. Although values of this ratio are significantly elevated in IIH, somewhat surprisingly, serum 24,25-(OH)2 D3 remains detectable. Read More
