Single-nucleotide polymorphisms may cause erroneous results in primer-introduced restriction enzyme analyses: a case of molecular misdiagnosis of homozygous vs heterozygous familial hypercholesterolemia.

Abstract excerpt

PCR amplification followed by a primer introduced restriction analysis PCR (PIRA-PCR) is a widely used method to detect point mutations. Usually the artificial RFLP is created by siting one nucleotide mismatch near the 3; end of the primer. This does not alter the hybrization of the primer to the target DNA sequence. Unfortunately, unexpected single nucleotide polymorphisms (SNPs) may lead to additional...
