  • Publication number: 20020091248
    Abstract: The present invention discloses the amino acid and nucleic acid sequences of a new CNGC and Myosin that map to the region of the human chromosome associated with Bardet-Biedl Syndrome. Cyclic nucleotide gated channels (CNGCs) comprise a family of multimeric protein ion channels that open in response to the binding of a cyclic nucleotide to an intracellular domain. The two new proteins, CNGC-15 and Myosin IXa, are useful in the study, diagnosis and treatment of Bardet-Biedl Syndrome and Usher Syndrome. Other indications that can be treated by CNGC-15 and/or Myosin IXa polypeptides, or agonists or antagonists include hearing loss, retinis pigmentosa, obesity, hypogonadism, sterility, polydactyly, brachydactyly, syndactyly, mental retardation, renal abnormalities, hypertension, diabetes and cardiovascular abnormalities.
