From Genotypes of Immunoglobulin Constant Heavy G Chains (Fcγ) (GM) Genes (IGHG) to Phenotypes in Childhood Asthma.
Background: IgE-mediated allergy is associated with immunoglobulin heavy constant G chain (Fcγ) (GM) genes (IGHG) on chromosome 14q32.3. Investigation of the alternative GM allotypes of γ3, γ1 and γ2 chains has disclosed new structural and functional IgG subclasses and B-cell variants, with possible effects on childhood asthma. Objective: To investigate different IGHG (GM) gene complexes in a
