We analyzed nine DM2 patients (six males and three females, mean age = 46.4 ± 20 years) with existing molecular diagnoses based on a combination of PCR-based approaches (SR-PCR, LR-PCR, and QP-PCR) to detect the presence of (CCTG)n expansions in the CNBP gene (Table 1). This evidence concerns the gene CNBP and myotonic dystrophy type 2.
