In human genetic identification the selection of highly polymorphic markers it is very important in order to obtain a high discrimination power even when the number of loci is limited. STR typing continues to be the most robust and reliable method for samples with small amounts of purified and non-degraded DNA. Nonetheless, STR typing has some limitations, such as large amplicon sizes between 150 and 450 base pairs, which can contribute for poor results in challenging forensic samples [ [1] Manta F.
