When all other FABPs expressed in MM cells (FABP6, FABP3, and FABP4) were examined, only FABP6 also affected hazard ratios (although effect sizes were not as large as FABP5) for PFS (HR:1.48; CI 1.172, 1.869) and OS (HR:1.837, CI: 1.347, 2.504), indicating that it may also be a biomarker for worse outcomes (Figure 8—figure supplement 2). Here, FABP5 is linked to Miyoshi myopathy.
