Abstract: Information regarding the ancestral and geographical origins of biological evidence samples may be useful for crime investigators as they narrow down the possible donors of the sample. A method for simultaneous analysis of seven biallelic markers (M130, M131, M57, M125, M175, M122, and M134) was developed for forensic application. M57, M125, and M131 are included to identify haplogroups inferred as having originated in the Japanese archipelago. Our method employs allele-specific PCR and fragment analysis using fluorescently labeled primers and capillary electrophoresis. This method can be used to assign a haplogroup from both of degraded male DNA samples and DNA samples containing a mixture of female and male DNA by designing PCR primers that generate small amplicons and are highly specific for targets on the Y chromosome. A total of 1,346 samples from Japanese males collected from the four major islands and Okinawa island were classified into seven Y binary haplogroups, i.e., C-M130, C-M131, D-M57, D-M125, O-M175, O-M122, and O-M134, and a "no-mutation detected" group; and their frequencies were 0.0617, 0.0565, 0.1441, 0.182, 0.3418, 0.11, 0.0847, and 0.0193, respectively. Samples of "no-mutation detected" were further analyzed by direct sequencing for identification of the major haplogroup to which they belong. Along with the haplogroup data, we report haplotype data for the 16 Y-STR markers included in the AmpFISTR Yfiler TM PCR amplification kit (Applied Biosystems). These data will be useful in the prediction of haplogroups based on Y-STR haplotypes. Tables, figures, and references (Published Abstract)
