| Abstract: | A possible approach to try to recover information from degraded DNA is to reduce the size of the PCR products by designing primers that bind as close as possible to the STR repeat region, known as miniSTRs. Allele frequencies and forensic parameters for the six miniSTRs loci D1S1677, D2S441, D4S2364, D10S1248, D14S1434 and D22S1045 were investigated in a sample group consisting of 228 anonymous apparently healthy unrelated individuals living in North of Portugal. The results show that all loci were in Hardy–Weinberg equilibrium. The combined power of discrimination and power of exclusion for the six loci were 0.99999 and 0.9789, respectively. All but one (D4S2364) loci showed a moderate degree of polymorphism (observed heterozygosity >0.6). The allele sizes ranged between 66 and 118 bp in our population, which is beneficial for typing degraded samples than those of a commercial STR kit. |
