A procedure based on selective hybridization with allele-specific
oligonucleotides was developed for typing apolipoprotein E variants from
human genomic DNAs. Two sets of oligonucleotides were synthesized and used
to discriminate either between epsilon 3 and epsilon 4 alleles or between
epsilon 3 and epsilon 2 alleles. Combination of the allele- specific
oligonucleotide hybridization with the method for in vitro DNA
amplification (Polymerase Chain Reaction) Saiki, R. K. et al. 1985.
Science, 230: 1350-1354) (1) dramatically improved the sensitivity and the
reliability of the procedure. Adaptation of a simple strategy involving
direct cloning and DNA sequencing of in vitro amplified DNA enables rapid
identification of any mutation within the apoE gene area encoding the
receptor binding domain.
