Whole blood samples were collected from 170 unrelated healthy individuals living in the North Italy. Genomic DNA was extracted using GenomicPrep Blood DNA Isolation Kit (Amersham-Pharmacia-Biotech, Milano, Italy) and its concentration was determined spectrophotometrically. Two to five ng of target DNA was amplified in singleplex for FGA and D8S1179, while duplex amplification was adopting for D13S317/D16S539 and D5S818/D7S820. PCR amplification conditions were the same for all six loci and the program of amplification were carried out in a GeneAmp® PCR System 9700 Thermal Cycler (PE-Biosystems, Foster City, CA). The amplified products were separated and detected using the A.L.F. express DNA sequencer (Pharmacia-Biotech, Uppsula, Sweden). Allele designation was established following the recommendations of the DNA commission of the ISFH (1). Statistical analysis was performed as previously reported (2) by a computer program made from the authors using Excel spread sheets.
