title: [Polymorphic markers of GNB3 (C825T), AGTR1 (A1166C) and ACE (A2350G and I/D) genes in patients with arterial hypertension combined with diabetes mellitus type 2].
abstract: OBJECTIVE
  To elicit correlations of polymorphic markers of GNB3 (C825T), AGTR1 (A1166C), ACE (A2350G and I/D) genes with arterial pressure, left ventricular hypertrophy (LVH) and blood concentrations of proinflammatory cytokines in hypertensive patients with diabetes mellitus type 2 (DM2).
  
  
  METHODS
  Clinical parameters (24-h arterial pressure profile, echocardiographic findings, immunoenzymes level) were studied in 89 hypertensive patients with DM2. These patients had different genotypes by the studied allele variants of the genes determined by polymerase chain reaction.
  
  
  RESULTS
  Polymorphism of A1166C gene of type 1 vascular receptor of angiotensin II (AGTR1) contributes to formation of arterial hypertension (AH) signs diversity in DM2 patients. GNB3, a gene C825T polymorphic marker, showed a correlation with diastolic arterial pressure but this variant of the gene locus is not associated with LVH. However, G-allele of ACE gene contributes much to appearance of this pathological sign. Mean values of IL-1beta and TNF-alpha as well as the presence of LVH depended on genotypes by ACE gene (polymorphism I/D).
  
  
  CONCLUSIONS
  Polymorphic markers of ACE and GNB3 candidate genes influence clinical diversity of pathological signs in DM2 patients through modification of AH and LVH severity and the level of proinflammatory cytokines.
