Abstract:

In the course of routine genotyping of forensic reference samples by multiplex PCR, an allelic drop-out due to mutations in the primer binding regions of the highly polymorphic STR marker ACTBP2 was observed in 17 samples. The variation rate was estimated to be 0.0014 (95% confidence interval: 0.0006–0.003). The most frequently found mutation was an G to A transition in the reverse primer binding region which was present in 14 out of 17 cases. To overcome the problem we have added a modified reverse primer to different multiplex kits that led to the correct genotype.
