The correlation analysis showed that samples with a lower CD28+ frequency in MAITs cells had a higher perforin-positive MAIT frequency (r = −0.209, p = 0.0001; Fig. 4c); furthermore, the extent of correlation was much stronger in the ME-MM group compared to the ME-SA group (r = −0.429, p < 0.0001 for MM, r = −0.044, p = 0.529 for SA; Fig. 4c). The gene discussed is PRF1; the disease is Miyoshi myopathy.
