Cow’s milk is one of the most frequent food allergies among Atlanta’s babies and young children. While most children outgrow their allergies by the time they reach adulthood, a milk allergy poses the risk of anaphylaxis. Genetics is often considered while seeking to discover the risk factors involved in food allergies. Is a milk allergy inherited, and what other variables might cause allergic reactions?
Does a Milk Allergy Run in Families?
If one or both parents have a milk allergy, their kid is more likely to get one as well. Most children will exhibit allergy symptoms before the age of five, while allergic responses may occur at any age. While having a family member with an allergy increases a child’s chances of getting symptoms, most newborns with allergies do not have an allergy-related family history. This is why parents should be cautious and see an allergist if they notice any troubling symptoms.
Similarly, genetic linkages exist in persons who are lactose intolerant. There are distinctions between milk allergies and intolerance, with allergies presenting a more significant risk. Furthermore, intolerance is more common in adults than in youngsters.
Studies Into Milk Allergies and Genetics
While the heritability of milk allergies has been shown, research into genetic variables is currently underway. One assessment of 32 food allergy research found that factors such as small sample numbers restricted the credibility of the results.
In a promising investigation, two single nucleotide polymorphisms (SNPs) were shown to be associated with cow’s milk allergy in children. SNPs are basically a form of common genetic variation. As a result, their existence might be utilized to predict the risk of a youngster exhibiting milk allergy symptoms. The SNP rs17616434 (P =.002) was identified near the toll-like receptor 6 (TLR6) gene in the aforementioned research, while the SNP rs2069772 (P =.038) was located in the interleukin 2 (IL2) locus.
Risk Factors Associated With Milk Allergies
While genetics play a part in milk allergies, other variables might predict whether a person will develop symptoms. Children are significantly more often than adults to suffer from milk allergies. If a person has other allergies or asthma, the likelihood of developing a milk allergy increases. Finally, food allergies are more common in atopic dermatitis youngsters.
People will naturally be concerned about allergic responses to milk or other meals. However, the effect of an allergy may be reduced with the use of drugs and oral immunotherapy treatment.

Are you born with a milk allergy?
Few kids have genuine lactose intolerance, which is a rare hereditary disorder in which they are born with no lactase enzymes at all. (This is called primary lactose intolerance.) Many individuals, however, acquire lactose intolerance later in life, beyond the age of five.

Are allergies hereditary?
Allergies are commonly genetic, which means they are handed down via DNA from parents to their children. However, just because a parent has allergies does not guarantee that their children will as well.
