Sequence analysis and characterization of stutter products at the tetranucleotide repeat locus vWA.

Abstract excerpt

The PCR amplification of tetranucleotide short tandem repeat (STR) loci typically produces a minor product band 4 bp shorter than the corresponding main allele band; this is referred to as the stutter band. Sequence analysis of the main and stutter bands for two sample alleles of the STR locus vWA reveals that the stutter band lacks one repeat unit relative to the main allele. Sequencing results also indicate...
