    ### Instruction:
    What are the genetic changes related to autosomal dominant hypocalcemia ?
    ### Response:
    Autosomal dominant hypocalcemia is primarily caused by mutations in the CASR gene; these cases are known as type 1. A small percentage of cases, known as type 2, are caused by mutations in the GNA11 gene. The proteins produced from these genes work together to regulate the amount of calcium in the blood.
