  5. Muscular Dystrophy Progressive degeneration & weakness of skeletal muscles. Some are affected more severely than others. Many forms of MD

  6. Down Syndrome – usually caused by trisomy of chromosome #21

  7. Cystic Fibrosis Formation of thick sticky mucuc that blocks respiration & digestive functions. Meds & treatment available, most people affected do not live past 40 years old. Usually have many respiratory infections and difficulty breathing.

  8. PKU Every state tests for this trait. Treatable with diet changes. Missing or ineffective enzyme for breaking down phenylalanine. Can cause brain damage & other problems if untreated.

  9. Miscellaneous Disorders WARNING!!! Some pictures are graphic & disturbing!!

  10. Cri Du Chat Syndrome Caused by missing piece of chromosome 5. High pitched “cat cry” Weak muscle tone Delayed development
