Can Allergies Be Found in DNA?

DNA is an incredible feature that makes each one of us unique. Our own genetic “fingerprints” differentiate each person from one another.

Not only do we share DNA with our ancestors, but we also can learn much about ourselves, our traits, and even our health through DNA.

But can DNA show us what we may be allergic to? Here is everything you need to know about whether or not allergies can be found in DNA:

What are Allergies?

Allergies happen when your body reacts to a foreign substance as it is introduced to you. Your immune system produces antibodies to keep you healthy—but when your antibodies identify a specific allergen that is harmful that actually is not harmful, you get an allergic response.

When you come into contact with this specific allergen, your immune system will respond in a way to protect and alert you that there is a threat. This can happen in a variety of ways.

Common Allergy Symptoms

There are a number of common allergy symptoms that can provide you with information about what you may be allergic to. The most common allergy symptoms include but are not limited to:

·       Hay fever—or allergic rhinitis

·       Runny or congested nose

·       Watery, swollen, or red eyes

·       Sneezing

·       Itching of the eyes, the roof of the mouth, or the nose

Food allergies can differ. The most common food allergy symptoms include but are not limited to:

·       Swelling of the tongue, lips, throat, or face

·       Tingling in the mouth

·       Anaphylaxis

·       Hives

Drug allergies can take similar forms but are important to know as well. They can include:

·       Rash

·       Facial swelling

·       Itchy skin

·       Hives

·       Wheezing

·       Anaphylaxis

It is incredibly important to take immediate action should you experience a severe allergic reaction to something. Call your medical physician immediately!

Can Allergies Be Found in Your DNA?

One of the true wonders of the world is where we come from. Our DNA can pinpoint to almost exact preciseness where our ancestors came from and roamed in the world. We are passed down many traits such as blood, physical and personality traits, hair and eye colors, and more. We can also find what medical issues we may be predisposed to. Allergies can also fall in line with this notion.

In short, YES, DNA can reveal allergies. Your at-home sample can provide the much-needed information that can identify the genetic predisposition you have to the development of allergies. It can also determine the hypersensitivity of your specific immune system.

Your DNA can tell you your potential response to allergens, autoimmune diseases or atopic dermatitis, predisposition to asthma, and more. A study in the UK offered a potential link between specific DNA genetic markers and children born during a certain season. This can show a higher chance of developing allergies.

Although not 100%, the analysis of DNA can identify potential genetic and environmental factors in the development of food allergies. Food sensitivities, however, cannot be determined based on DNA.
