In the EFS, B2M (HR = 1.38, 95% CI 1.01–1.88; P = 4.22E−02), MRI (HR = 1.40, 95% CI 1.07–1.84; P = 1.47E−02), BMPC (HR = 1.39, 95% CI 1.01–1.92; P = 4.56E−02) and BCAR3 (HR = 0.66, 95% CI 0.5–0.88; P = 5.17E−03) are prognostic factors for MM. This evidence concerns the gene BCAR3 and Miyoshi myopathy.
