Hello to everyone here, I've been living with a peanut allergy since childhood and now that I have a 1 year old I'm really worried about him having a peanut allergy as well. I've had severe reactions since I was a child and to think that he may go through that as well is heartbreaking. Does anyone here know if a peanut allergy is genetic?

From what I've read I think yes peanut allergies are genetic and can be inherited.

Yes, doctors told my parents that it's genetic. My parents had us tested when we were little and I was the "lucky" once to get it. My siblings are in the clear.

Our 11 year old daughter has severe nut allergies (outgrew egg allergy). We got our son tested for allergies at 5 months old and immediately started peanut butter and then almond butter. He is allergic to dairy, eggs and cashews though. Both kids were born emergency csection due to distress and were given cows milk formula. Our son took it only for a week (then breast milk for 15 mos) whereas our daughter took both formula and breast milk from birth till 8 months. So there is some merit to early and continued exposure to reduce reactions (unless the body has already developed antibodies; hence the scratch tests).

My side of the family has severe ragweed allergies, so food allergies are something new with this generation.

This is a question I asked the Allergy Specialist when I saw her the other month, and she said no, it isn't genetic.

Here is something I came across in a science journal:

"Researchers have pinpointed a new gene associated with peanut allergy, offering further evidence that genes play a role in the development of food allergies and opening the door to future research, improved diagnostics and new treatment options."
