The role of angiotensin-converting enzyme (ACE) gene I/D polymorphism in development of cardiovascular pathology (CVP), metabolic syndrom and insulin-independent diabet associated with such metabolic disorders as glucose intolerance and hyperglicemia, intolerance to insulin and hyperinsulinemia, dyslipiproteinemia (DLP) and obesity is discussed. Most of authors consider D-allel and DD genotype to be assosiated with development of DLP and such CVP as ishemic heart disease and myocardial infarction.
