Objective: Using high resolution melting (HRM) to analysis MDR1 C3435T in people exposed to benzene.
Methods: Restriction fragment length polymorphism (RFLP) was utilized to detect the polymorphism of MDR1 3435 in 121 benzene-exposed workers, and the results were compared with the HRM in 10% samples and were confirmed with direct sequencing for six people in them.
Results: By direct sequencing, consistent results of benzene-exposed workers with RFLP or HRM were got. The new high resolution melting curve analysis is more efficient, more convenient, and cheaper than RFLP.
Conclusion: High-resolution melting analysis provides a valid approach to efficiently detect DNA genetic diagnosis, which is suitable for detect susceptible genes in occupational surveillance.
