Myotonia Congenita - Health Centers News Story - WCVB Boston |
 | | Myotonia congenita is an inheritable congenital (present from birth) disorder characterized by slow relaxation of voluntary muscles, such as those in the legs. |
 | | Myotonia congenita can be either an autosomal dominant or autosomal recessive disease. |
 | | The cause of myotonia congenita is believed to be an abnormality in the chloride channels of muscle cells (chloride ions are required for a muscle to relax). |
