Abstract:

The knowledge of mutation rate at Y-STR markers is essential in forensic casework, especially kinship genetic studies. In the present study, one hundred father–son pairs from Chinese Han population were typed with 53 Y STR markers (38 conventional markers and 15 rapidly mutating markers). A total of 28 mutations were detected in 6201 allele transfers. All were one-step mutation. The average estimated mutation rate of 15 rapidly mutating (RM) Y-STRs was 1.05 × 10−2 (95% CI 5.45 × 10−3–1.39 × 10−2), while the average mutation rate of 38 conventional Y-STRs was 1.46 × 10−3 (95% CI 3.07 × 10−4–2.59 × 10−3). In summary, the average mutation rate of 15 RM Y-STRs seemed to be seven times higher than that of 38 conventional Y-STRs.
