Abstract
Hypervariable tandem repetitive regions in human DNA are proving to be increasingly useful for genetic analysis in humans. We chose four single locus probes (SLP; MS1, MS43, MS8 and g3) for a validation test among Koreans. The specimens were from 216 unrelated individuals and 33 paternity inclusion families. Extracted DNA from EDTA blood was restricted by Hinfl and electrophoresed in 0.7% agarose gel, transferred and hybridized with chemiluminescent probes. Heterozygosity was over 90% by all of the probes. Total numbers of unassignable mutant bands from 33 paternity inclusion cases were 5, and the highest mutation rate was determined in probe MS1(0.045). The probability of having the same DNA band between two unrelated individuals was 5.7 x 10(-10) when four SLPs were used at the same time. The data presented here on allele frequencies and mutation rates provide preliminary data supporting the validity of these probes in paternity analysis and forensic investigators in the Korean population.
