Profiling a North-East Italian Population by Four Highly Polymorphic DNA Probes

After the forensic validation of the SBA (Southern Blot Analysis), the use of SLPs (single locus probes) has been used in the forensic laboratory for personal identification and paternity testing since the end of the 1980s. Even if expensive and time consuming, the SBA remains the most informative approach in some circumstances, for example in those paternity cases where either the alleged father is unavailable or the paternity index achieved by PCR-based polymorphisms is too low to prove paternity. In this work the allele frequenciy distributions at four highly polymorphic loci (D1S7, D7S21, D12S11 and D7S22) are described in a population living in the Trieste and Gorizia areas (North-East Italy).
