Association of REL Polymorphism with Cow's Milk Proteins Allergy in Pediatric Algerian Population. Association REL Polymorphism with Cow's Milk Proteins Allergy.

Introduction: Cow's milk proteins allergy (CMPA) pathogenesis involves complex immunological mechanisms with the participation of several cells and molecules involved in food allergy. The association of polymorphisms in the interleukin 4, Forkhead box P3 and the avian reticuloendotheliosis genes was investigated in an infant population with CMPA of Western Algeria. Materials and methods: We obtained DNA and clinical data from milk allergic subjects during active phase and from a group of non-atopic control subjects. Results: Our findings showed that the allele G of the cRel gene intronic polymorphism at +7883 positions was significantly higher among cow's milk proteins allergic patients compared to control subjects. Conclusion: The results of this study suggest a possible association of CMPA with cRel G+7883T polymorphism.
