Genetic Risk Factors For Allergies

Allergies are often hereditary. If your parents are affected by allergies, you are more likely to develop an allergy as well. This article will explain how genetic risk factors for allergies come about.

The following are some of the most likely factors influencing the likelihood of a person being affected by allergies.

Allergic Parents

A parent suffering from allergy is likely to transfer the allergy to the son or daughter. But the allergy that the child develops is not always the same one as the parent is suffering from. Therefore, allergies are likely to develop irregularities when passed on from a parent to a child.

Identical Twins

Because of the familial reasons for the way allergies come about, identical twins are more likely to suffer from same allergies than non-identical twins.


When you are young, you are more likely to develop an allergy than when you are a grown up. The likelihood of developing asthma or hay fewer, for instance, is most likely when you are under the age of ten.


Gender is a factor in how likely it is that an allergy develops. For most allergies, boys are more likely to be affected. However, for some allergies, like asthma, girls are more at risk. Therefore, the risk of developing an allergy varies according to what the allergy is and gender.


Racial background plays a part in the likelihood of developing an allergy. However, it has been difficult to asses precisely what the racial factors affecting the development of allergies are. This is because environmental factors play a large role in the what allergies a person suffers from. Also race factors are difficult to quantify because of migration, which might expose people to a higher risk of an allergy because of the change in environment that the people live in.
