Purpose: Preimplantation genetic diagnosis (PGD) has been performed for deletion and point mutation type of Duchenne muscular dystrophy (DMD). Our aim was to develop a PGD technique, not yet established, to directly detect duplication mutation instead of substitute diagnosis similar to gender determination. Methods: Our method is based on comparative quantification using conventional duplex PCR, real-time PCR and gender determination. We evaluated this method in single lymphocytes from a duplication type of DMD patient and a normal male. Results: There was a significant difference in the mean values of the ratios (the mutation locus/a normal reference): mean value ± SE was 1.84 ± 0.15 in the duplication patient, and 1.00 ± 0.09 in the normal male (p < 0.001). Conclusion: It is suggested that our comparative quantification method could be a new option in PGD for carriers with duplication mutation who wish to have an unaffected son.
