 AB    Genetic analysis of 170 subjects in 11 extended Amish families revealed
       evidence for linkage of five markers in chromosome 5q31.1 with a gene
       controlling total serum IgE levels. No linkage was found between these
       markers and specific IgE antibody levels. Analysis of total IgE within a
       subset of 128 IgE-antibody-negative sib pairs confirmed evidence for
       linkage to 5q31.1, especially IL4 (p = 4 x 10(-6)). These and other data
       suggest that IL4 or a nearby gene regulates IgE production in a
       non-antigen-specific (noncognate) fashion and provide evidence for a
       possible link between asthma and the IL4 gene.
