In our study, the CRP levels in obese patients with T2DM [8.70 (4.2–13.9) mmol/l] and in obese patients without T2DM [10.2 (8.25–16.10) mmol/L] were higher than the control value (p < 0.05), which indicates the presence of systemic inflammation in these categories of patients (Table 3). The gene discussed is CRP; the disease is type 2 diabetes mellitus.
