MCL1 and Miyoshi myopathy: Therefore, we further analyzed the expression of BCL2, BCL2L1, and MCL1 (i.e., BCL2 family members) in an extended cohort of samples derived from BM of AL amyloidosis patients (range 57–64 samples), and MM patients (range 50–59) (depending on the availability of biological material) and compared them to the expression of these genes in BM samples attained from seven HCs who had hip replacement.
