TIMP-1 correlated with abnormal unilateral and bilateral vibratory sense foot perception (r = −0.49 and r = −0.51, respectively), foot neuropathy impairment assessment score (NIA; r = −0.55), neuropathy symptom assessment score (r = 0.42), microalbuminuria (r = 0.50) and eGFR (r = −0.45). This evidence concerns the gene TIMP1 and neuropathy.
