FAM225A and myasthenia gravis: To further clarify the association of FAM225A and clinical scores, we conducted correlation analysis between quantitative myasthenia gravis (QMG) score and the relative expression of FAM225A, and found that FAM225A in triple-SN MG patients was negative correlation with QMG score (R = −0.874, p-value <0.001, Figure 4B).
