A two-step polymerase chain reaction (PCR) method for the rapid detection
of the apolipoprotein B(Arg3500----Gln) mutation in a mixture of pooled
blood samples is described. In the first step PCR, a short gene fragment
surrounding codon 3500 is amplified. Subsequently the reaction product is
subjected to a second amplification in which a mutation-specific primer is
used. A PCR product is generated only if the mutant sequence is present in
the DNA pool. Individuals carrying the mutation can then be identified by
PCR with mutagenic primers and MspI restriction typing, essentially as
described by Hansen et al. (J. Lipid Res. 1991. 32: 1229-1233).
