Haplotyping by double PCR amplification of specific alleles.

ABSTRACT

Haplotypes are useful in population genetics and medicine. Determining haplotypes in the absence of DNA samples from appropriate family members can be difficult and laborious. We have developed a rapid and reproducible method for haplotyping an individual in the absence of relatives. The method utilizes pairs of allele-specific PCR primers to differentially amplify each haplotype. Four amplifications can distinguish the haplotypes produced by two biallelic polymorphisms.
