Geneticists are medical doctors who specialize in the study of human genes (see full Glossary) and chromosomes (see ECI Glossary). They study heredity factors (the things a person inherits from family), family histories and genetic mutations (or changes). They treat individuals who have genetic disorders and offer:

• Genetic testing to determine whether or not a person has a genetic or chromosomal disorder. This includes:
  • Blood tests (Fig. 1);
  • X-rays (Fig. 2);
  • Ultrasounds (Fig. 3);
  • Genetic counseling to families who have a member with a genetic condition or disorder:
    • Understanding  how likely it is that other members of the family will develop or have the same genetic disorder;
    • Understanding how likely it is that siblings may have children who have the same genetic disorder;
    • Understanding the difference between recessive (see full Glossary) and dominant (see full Glossary) genes;
    • Understanding the preventive measures that can decrease genetic disorders.
    • Preventive services: For instance, by checking for genetic conditions such as PKU (see full Glossary), geneticists can diagnose children right away after birth, and offer intervention options to families.
