9 gene influences cardiac diseases
Two independent groups of researchers from Canada and Iceland have found out three widespread genetic mutations, which considerably raise the risk of cardiovascular diseases at white Europeans and Americans.
During one of the researches experts of University of Ottawa (Canada) have analyzed samples of blood of 28 thousand patients with cardiovascular diseases, and healthy people who have made the control group. In result two mononucleotide mutations of genes of the 9-th chromosomes pair have been found, which sick participants have much more often.
According to the researchers, these genes are rather often met: more than half of Europeans are carriers of one copy of one of them, and a quarter have them in both chromosomes of 9-th pair.
At the same time the employee of University of Sheffield Tim Chico marks, that, in spite the great value of the information received by researchers, as a whole, the risk of cardiovascular diseases is determined not so much by genes, but by many factors of an environment: smoking, meal, an inactive way of life, etc. “Whatever are our genes, we can always lower risk of illnesses having changed a way of life ” - considers he.
