[Paternity test with single locus DNA probes].
Seven kinds of DNA probes recognizing hypervariable DNA loci were applied to 28 cases of paternity test, involving two cases in which the putative fathers had died. The combinations of probe and restriction enzyme are as follows; MR24/1-HinfI, 3'Globin-PvuII, Ha-ras-PvuII, Mucin-PvuII, D2S44 (pYNH24)-MspI, D17S30 (pYNZ22)-MspI, D1S57 (pYNZ2)-RsaI. The reported number of the alleles are 37, 39, 5, 10, 33, 15, and 5, respectively. Those probes lie on different chromosomes except D1S57 on 1p and Mucin on 1q21. Exclusion probability (EP) and paternity index (PI) were calculated from the allele frequencies in Japanese population reported by Yokoi et al. Cumulative EP from 7 DNA probes was 0.999932, and cumulative PI ranged from 7.3 X 10(6) to 947. Also, cumulative EP from 17 kinds of conventional blood group markers (CBGM) was 0.9776, and cumulative PI ranged from 1290 to 0.11. Total EP from 7 DNA probes and CBGM was 0.999998478. Cumulative PI from 7 DNA probes were 5 to 2,000,000 times higher than that from CBGM. The single locus hypervariable DNA polymorphisms are considered to be informative for paternity test.
