Are allergies genetic? Genetic variants in filaggrin are common in the population, and although results are conflicting as to whether these variants increase risk of food allergy, the strongest proof currently resides for an association between loss-of-function variants in this gene and peanut allergy specifically.

Ara h 2, the most potent peanut allergenic protein, was selected as a model to demonstrate the feasibility of the post-transcriptional gene silencing model and stable expression of the truncated Ara h 2 transgene throughout the development of the plants. They scanned approximately 1 million genetic markers across the human genome, searching for clues to which genes might contribute to increased risk of developing food allergies, including peanut. Interestingly, this is also the same location that predisposes people to … But for peanut allergy, they identified certain regions within the human leukocyte antigen (HLA) that likely contribute a significant genetic risk.
