Allele-specific enzymatic amplification of beta-globin genomic DNA for diagnosis of sickle cell anemia.

A rapid nonradioactive approach to the diagnosis of sickle cell anemia is described based on an allele-specific polymerase chain reaction (ASPCR). This method allows direct detection of the normal or the sickle cell beta-globin allele in genomic DNA without additional steps of probe hybridization, ligation, or restriction enzyme cleavage. Two allele… CONTINUE READING
