Panel Cardio

Diabetes mellitus is an important risk factor for cardiovascular diseases [1,2]. It increases the risk of atherosclerosis and infarction [3,4].

Among the leading causes are hyperglycemia, hyper-lipidemia (in particular small, low-density lipoproteins of cholesterol) and hypertension associated with diabetes [5]. On the basis of familiarity studies, it has been shown that a considerable part of the cardiovascular risk is under genetic factors control both in non-diabetic [6,7], and in diabetic subjects [8,9].

The CARDIO panel analyzes 8 genetic polymorphisms (or SNPs) whose presence is associated with a greater probability of developing diabetic cardiomyopathy. Genes with variants studied within the CARDIO panel are listed hereafter:


  1. ADIPOQ: gene that encodes a hormone secreted by adipocytes and regulating the catabolism of fatty acids and glucose.
  2. TNFAIP3: gene that encodes an enzyme involved in immune and inflammatory responses.
  3. TNFα: gene that encodes a multifunctional pro-inflammatory cytokine belonging to the TNF superfamily. This cytokine is involved in the regulation of a broad spectrum of biological processes, including proliferation, differentiation, cell apoptosis, lipid metabolism and coagulation.
  4. Introne9p21: gene not encoding for proteins. These polymorphisms have been associated with the onset of diabetic cardiomyopathy.
  5. ADIPOR1: gene that encodes the adiponectin receptor. Binding with adiponectin activates a cellular signaling pathway acting on fatty acid oxidation levels and insulin sensitivity.

Recommended for anyone who wants to know genetic predisposition to develop diabetic cardiomyopathy.
