Detection of the promoter polymorphism.
PCR-amplified DNA from 19 individuals was subjected to sequence analysis using dye-primer sequencing. A heterozygous polymorphism was detected in the DNA from one individual. Equal amounts of thymine and cytosine peaks indicate heterozygosity at position −37 of theCCR3 gene (as indicated by the arrow). Y indicates thymine and cytosine.
