Indel polymorphisms—An additional set of markers on the X-chromosome

Insertion/deletion polymorphisms (indels) are diallelic markers which are underutilised in the forensic science. The simple structure of diallelic markers enables them to generate very short amplicons which facilitate successful typing of degraded DNA samples. Introducing indels into the ensemble of kinship testing tools we here present a panel of 26 X-chromosome indels, which can be amplified and analysed using 5 multiplex PCR setups.
