Abstract
We have used a cDNA probe for the human IgE receptor alpha chain to determine the chromosomal location for the human gene. A combination of Southern blot analysis of panels of somatic-cell hybrid DNAs and chromosomal in situ hybridization has localized the gene to the long arm of chromosome 1 at q21-q23. With this cDNA probe, we have also identified an RsaI RFLP which is inherited in a Mendelian fashion. This polymorphic marker on chromosome 1 should be valuable for studies directed at the identification both of diseases involving the IgE receptor alpha chain and of genetic factors affecting the allergic response.
