Autosomal dominant inheritance means an abnormal gene from one parent can cause disease, even though the matching gene from the other parent is normal. The abnormal gene dominates. In this book, the authors present new research in autosomal dominant disorders. Topics discussed include the pathophysiology and treatment of autosomal polycystic kidney disease; hereditary haemorrhagic telangiectasia or Rendu-Osler-Weber Syndrome; osteogenesis imperfecta; and autosomal dominant disorders associated with breast cancer.
