FRMD3 mRNA expression did not correlate with age (r2 = 0.11; P = 0.305), and did not differ between females and males [0.31 (−1.92 to 2.05) vs. 0.12 (−2.70 to 2.00); P = 0.200], between patients with or without hypertension [0.47 (−2.05 to 2.05) vs. −0.21 (−2.70 to 1.99); P = 0.077] and between patients with or without diabetes [0.37 (−2.70 to 1.98) vs. 0.16 (−2.22 to 2.05); P = 0.779]. Here, FRMD3 is linked to diabetes mellitus.
