What Diseases Can Be Found With Genetic Testing?

Thanks to the wonders of scientific advancements, genetic or DNA testing can help give us a sneak peek into what our bodies and even minds may need in order to thrive.

These tests don't just indicate areas of concern but they provide us with the opportunity to improve our lives by taking the necessary steps toward preventive healthcare. What can your DNA tell you about yourself and your health? In this article, we explore just that!

What Can a DNA Test Tell You About Your Health?

First things first – we need to ask ourselves what is DNA testing used for? A DNA test can uncover helpful information regarding certain illnesses and diseases that you may be predisposed to and various health factors such as genetic mutations or changes in the DNA that could lead to higher disease susceptibility.

DNA testing can also help healthcare practitioners to understand how your body reacts to certain medications. This is called pharmacogenomics and it can assist in creating a personalized approach to drug dosage and selection.

What Does Genetic Testing Look For?

There are various types of genetic variations a DNA test will look for, they are:

Single gene mutations

These are mutations in specific genes that are linked to inherited genetic disorders or that may be linked to an increased risk of developing certain diseases, such as the mutations associated with Huntington's disease or cystic fibrosis.

Chromosomal abnormalities

Any abnormalities in the chromosomes, such as alterations to the amount or structure of chromosomes can indicate conditions such as Down syndrome, Klinefelter syndrome, or Turner syndrome.

Genetic variants

A genetic test can help to pinpoint genetic variants that may lead to diseases, such as diabetes and heart disease, which sometimes involve a number of genetic and environmental factors involved.

Which Diseases Can Be Detected with Genetic Testing?

Cardiovascular Disorders

Genetic testing can identify mutations linked to cardiovascular disorders, such as familial hypercholesterolemia, atherosclerosis, and hypertrophic cardiomyopathy. Having this knowledge can help you to make the change necessary to prevent a major cardiovascular event.

Neurological Disorders

Genetic testing has been helpful in identifying various neurological disorders as well as identifying high risk in individuals, allowing them to seek out preventive treatment early on. These conditions include Huntington's disease, Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis (ALS).


Obesity is rife in many communities today due to poor lifestyle choices, such as an unhealthy diet and/or a sedentary lifestyle. If you have a BMI of, or higher than 30, you are classified as obese. DNA testing can help to identify an increased risk of obesity.

Age-related Macular Degeneration

AMD is a loss of vision in one or both eyes that often appears after the age of 60. This is one of the conditions for which high risk can be identified using a genetic test.


Psoriasis is a skin disease that creates inflamed, itchy, red rashes on the skin. The good news is that a predisposition to this condition can be detected through a genetic test. The test will identify mutations in the genes linked to Psoriasis.

Can At-home Genetic Tests Accurately Predict Health Risk?

At-home genetic tests are more popular now than ever because they allow individuals to gain control of their own health in a way that wasn't as easily accessible before.

No matter how accurate these tests may be, it's important to note that just because a test shows a predisposition for a certain disease or illness, it doesn't mean that all hope is lost! If anything. It can give you the power to take charge of your health by making a few key changes.
