NCIt definition : Human IL4R wild-type allele is located within 16p11.2-12.1 and is approximately 35
kb in length. This allele, which encodes interleukin-4 receptor subunit alpha protein,
plays a role in Th2 cell differentiation, immunoglobulin E (IgE) production and cellular
proliferation regulation. Allelic variants are associated with atopy. This condition
