[Application of AmpliType PM kit to forensic sciences].
Five genetic loci, low density lipoprotein (LDLR), glycophorin A (GYPA), hemoglobin G gammaglobin (HBGG), D7S8 and group specific component (GC), can be identified in a single step by the AmpliType PM kit. The kit uses multiplex PCR amplification and hybridization by a reverse dot blot method. To introduce the new marker system in forensic caseworks in Japan, a relevant Japanese population database must be established. In this context, the allele frequencies of the 5 genetic loci were determined for 246 unrelated Japanese. The allele frequencies were LDLR*A 0.173, LDLR*B 0.827, GYPA*A 0.528, GYPA*B 0.472, HBGG*A 0.352, HBGG*B 0.648, HBGG*C 0.000, D7S8*A 0.612, D7S8*B 0.388, GC*A 0.258, GC*B 0.504 and GC*C 0.238, respectively. In all 5 systems, the genotype frequencies are in good accordance with the Hardy-Weinberg expectations. The power of discrimination (PD) of LDLR, GYPA, HBGG, D7S8 and GC were 0.449, 0.624, 0.600, 0.612 and 0.788, respectively, resulting in a combined PD of 0.993, while these 5 DNA types could be determined from slaiva and semen. And the GYPA or GC genotypes were observed to have good relations with the MN and serum Gc phenotypes. The AmpliType PM kit was confirmed to be a reliable DNA typing system which was well suited for use in forensic sciences.
