The peripheral nervous system diseases related proteins, such as microtubule‐associated protein 4 (MAP4), myotubularin (MTM1), unconventional myosin‐Va (MYO5A), WAS/WASL‐interacting protein family member 1 (WIPF1), and ganglioside‐induced differentiation‐associated protein 1 (GDAP1) were also increased in T2DM‐MCI compared with T2DM‐nMCI (Figure 2c). This evidence concerns the gene GDAP1 and peripheral nervous system disorder.
