The observed CTLA4 rs231775 allele frequency 0.36 in the MM group was identical to the European control group (Figure 1A–C), while the LAG3 rs870849 allele frequency 0.59 was significantly higher in the MM group than in the European control group with rs870849 allele frequency 0.39 (Figure 1D–F). Here, CTLA4 is linked to Miyoshi myopathy.
