Specific genes cause many medical disorders. Even more, many other genes increase the tendency of a person to contract disorders. How does this happen? Remember that genes contain the information to build proteins, the basic building blocks of the human body. Mutated genes sometimes result in proteins that have restricted functionality or no functionality.

Scientists believe more than 4,000 diseases result from mutated genes inherited from one’s parents, including:

  • Down Syndrome
  • Fragile X Syndrome (common inherited cause of mental impairment)
  • Cystic fibrosis
  • Muscular dystrophy
  • Deafness
  • Breast cancer
  • Sickle-cell anemia
