Though the expression level of RORC or AHR was higher in ND MM patients (median=0.10, range, 0.01-0.25; median=0.48, range, 0.09-1.21, resp) compared to control group (median, 0.08; range, 0.003-0.43; median, 0.44; range, 0.11-0.99, resp), no statistical difference was found. Here, AHR is linked to Miyoshi myopathy.
