ABCC6 was expressed more highly in the MMD (compared to the non-MMD) vessels, and, taking advantage of the VSMC-specific marker a-SMA (Figure 5C), we observed strong colocalization between ABCC6 and a-SMA, indicating that ABCC6 was indeed expressed more highly in VSMCs in MMD. Here, SMN1 is linked to multiminicore myopathy.
