[Investigation of the genetics of allergic children, the second report--family study to determine the major gene in allergic disease using affected sib pair method].
Twenty-six families with allergic siblings were investigated to define the mode of inheritance of asthma and DF specific IgE antibody production in children. The affected sib pair method was used to establish the linkage between disease susceptibility genes and HLA antigens. The affected sib pair method revealed that in asthmatic families chi 2 = 4.9 (no significance) and in DF-specific IgE positive families chi 2 = 6.2 (p less than 0.05). This study suggests that the gene of DF-specific IgE antibody production is linked to HLA haplotypes, but the mode of inheritance of DF-specific IgE antibody production couldn't be defined.
