Abstract

Non-uniform phenotyping of five case work samples were observed in the D12S391 locus. The samples were typed at least twice with the AmpFℓSTR(®) NGM SElect™ PCR Amplification Kit and different alleles were called with GeneMapper(®) ID-X in the different experiments. Detailed analyses of the electropherograms suggested that the individuals were heterozygous with two alleles that differed in size by one nucleotide. This was confirmed by amplifying the samples with the PowerPlex(®) ESX 17 system. D12S391 is a complex STR with variable numbers of AGAT and AGAC repeats. Second generation sequencing revealed that separation of two alleles differing by one nucleotide in length was poor if the number of AGAT repeats in the short allele was higher than in the long allele. A total of 45 individuals with microvariants or off-ladder alleles in D12S391 were sequenced. Thirty different alleles were detected and sixteen of these were not previously reported.
