What is Genetic Counseling?

Genetic counseling is a medical process one can undergo, with the help of a genetic counselor, to learn more about inherited predispositions (or familial risk level) for developing certain medical conditions.

Where Can Genetic Counselors be Found?

Genetic counselors work in clinics, hospitals, genetics laboratories, research centers, prenatal centers and even insurance companies to help assess the potential hereditary health risks of families and individuals for different reasons.

Who Should Consider Genetic Counseling?

Anyone can seek genetic counseling to get a better look at potential health conditions they may be at higher risk of developing. People most likely to seek or be referred to genetic counselors may include:

  • Those who have been diagnosed with a disease such as cancer and want to learn how their genetics may impact the prognosis.
  • Those who have family members with certain types of cancer and wish to learn about specific cancer genes they may have inherited that may raise their personal cancer risk.
  • Those who belong to certain ethnic groups or geographical populations with higher instances of disease.
  • Older parents thinking about conceiving and want to know the risks involved.
  • People who want to check if their genetics are compatible before conceiving. For example, if both parents carry a gene specific to cystic fibrosis, the child will have a 25% chance of being born with the disease.
  • Those who’ve already had child born with a genetic disease such as congenital heart problems or cleft palate.
  • Those who’ve had a child with autism spectrum disorder or another developmental disorder and wish to learn more about the situation.
  • Those who have received an abnormal ultrasound report for their unborn child.

We’ve only scratched the surface of this complex, comprehensive process that can help shed light on a person’s personalized medical topography and risk level for disease or help with prenatal planning. Thanks for visiting DocChat!



How Well Can Genetics Predict Your Future?

Your genetics play an important role in helping predict potential health issues that  ‘run in the family’. Inherited genes work in tandem with other factors to make up your health situation. We will touch on some very common conditions that are heavily influenced by genetics.

Do Genes Cause Diseases?

Unless there is a clearly heritable disease that is derived through genetic mutations directly inherited from one or both parents, then no, genes aren’t usually the sole cause most conditions (but they do play a leading part). There is a reason family pools often share similar medical problems; inherited risk factors are passed down from generation to generation through common variant genes.

Other Risk Factors

Through extensive research using many different methods such as twin studies, medical scientists have identified a number of other risk factors that pair with genetics to cause diseases, the two main ones are:

  1. Environmental – potentially harmful elements or substances you’ve been exposed throughout your life or for a portion of it that may alter your DNA, such as too much sunlight or asbestos.
  2. Lifestyle habits – Our lifestyles also have a strong influence over possible health issues as well. Some of these habits include a good or bad diet, sedentary lifestyles versus getting regular exercise, as well as drinking heavily or smoking.

Common Conditions That Run in Families

According to NIH Senior Health, there are many diseases that run in families. This means the diseases aren’t directly caused by, but are heavily linked to familial genetic patterns. Some of these conditions include:

  • Alzheimer’s disease
  • Cardiovascular disease (high blood pressure, cholesterol, and conditions such as cardiomegaly and cardiomyophathy)
  • Stroke, blood clots and other similar conditions
  • Asthma and other lung diseases
  • Psoriasis
  • Cancer
  • Miscarriages and some birth defects
  • Arthritis
  • Depression and other mental health conditions
  • Diabetes

Early detection

Knowing your genetics can certainly help prevent or at least slow potential future health complications. For example, if you know there is a history of breast or ovarian cancer in your family, you can be tested for the BRCA1 and BRCA2 genes. Testing positive will put you at a 50% higher risk of developing these diseases. While this would be very frightening information to know, it would also be helpful so you can take adequate preventative measures such as diet, lifestyle, or in some cases a bilateral prophylactic mastectomy or salpingo-oophorectomy may be recommended to decrease chances.

Genetic Counseling

In genetic counseling, clinical geneticists will help you identify conditions that may be specific to you and your family, as well as help calculate the risks of you or your children in developing them. Genetic counselors can discuss possible birth complications high risk pregnant women may face. They can also help you make decisions about testing, treatment or preventative measures you can try.

What If You Don’t Know Your Genes?

If you were adopted, your familial health history may be tricky to track down. Some adoption agencies collect family health histories from birth parents who bring children in for adoption, but it can be hard to find out which agency to check. However, there is still some value in looking into your adoptive family’s history as it may show cultural, social and environmental risk factors you and your surrogate family may have in common because of your living situation and environment.
