Your family history holds key information about your past that can unlock clues about you or your children’s future health. Genetics is the branch of medicine that looks at how hereditary and genetic factors play a role in causing a disease, birth defects, or inherited susceptibility to a health problem such as cancer or heart disease. Almost all disease is a result of the interaction between our genes and the environment. Genetic specialists provide individuals and families with information about inherited diseases, how they are passed down in their family, and the implications to their health. Genetic services can include physical exams, health histories, diagnostic and laboratory tests, and genetic counseling. Genetics may be complicated, but we can help make it clearer. Genetic counselors and medical geneticists are specialists that are available to provide in-depth counseling about heritable disorders and determine if you could be at risk. Genetics can have an influence at any point in our lives.

Genetics can have an influence at any point in our lives.

Texans seek genetic services before and while pregnant to determine if the baby is at increased risk for birth defects and genetic conditions or if a medication or drug could affect the development of their baby. Birth defects are related to both genetic and environmental factors. A genetics professional can help if a birth defect is detected during a pregnancy. In addition, the Department of State Health Services (DSHS) operates a Teratogen Information Service to assist Texans in determining if a drug or environmental exposure could affect their pregnancy. A teratogen is defined as any medication, chemical, infectious disease or environmental exposure that could affect the development of a fetus.

All babies in Texas are tested at birth for certain rare disorders, hearing screening, and critical congenital heart disease. Newborn screening is a powerful tool for the early identification and treatment of certain disorders. In the United States it is estimated that 3-5% of all babies are born with a genetic condition, birth defect or intellectual disability. Five to ten percent of all children have learning or intellectual disabilities. Genetic factors play a role in many forms of  intellectual disabilities. If the exact cause of the intellectual disability can be determined, it could alter the medical management of the child.

Genetic services have evolved into testing adults for a genetic predisposition for such disorders as cancer and heart disease. Understanding the genetic causes of disease can help to develop better prevention and treatment strategies. Knowing your genetic health history can allow your physician to see the bigger picture.

It is important for all Texans to know their family medical history. Many health problems run in families because families live in the same environment, share the same habits, lifestyles and genes.

The U.S. Surgeon General encourages all families to learn more about their health history. A computer tool, called “My Family Health Portrait” has been developed to help families record their family tree and medical history.
