LINKAGE ANALYSIS OF IL-4 AND OTHER CHROMOSOME 5q31.1 MARKERS AND TOTAL SERUM IMMUNOGLOBULIN E (IgE) CONCENTRATIONS
1 Denver, CO
This group found evidence linking five markers in chromosome 5q31.1 with a gene modulating total serum IgE concentration in a sib-pair analysis of 170 individuals in 11 Amish families. Evidence was found for the linkage of 5q31. I and the IL-4 gene. Specific IgE concentrations were not linked to these markers. Thus, this study suggests that IL-4 or a nearby gene in 5q31.1 regulates overall IgE production.
