According to the conclusions of the scientists from the University of Leicester in England, the transmission of genes through chromosome Y. This is the only part of the DNA found in men.
DNA analysis carried out the research team of more than 3,000 men who are biologically unrelated in the UK. The result is found, 90 percent had a Y chromosome variants of two main groups namely haplogrup I and haplgrup R1b1b2.
Men who have a Y chromosome from haplogrup 1 has a 50 percent risk of coronary artery disease. Regardless of the risk of heart disease risk factors are common such as smoking, hypertension and high cholesterol. Furthermore, about 20 percent of men in the UK have this kind of chromosome.
“Studies on the genetic maps of disease susceptibility is very important. Furthermore we will analyze the Y chromosome in humans to search for specific genes and variants in direct relation with the disease,” says lead researcher Dr.Maciej Tomaszewski.
He added that the Y chromosome has been traditionally known only in determining the dominance of the male gender. Relation to heart disease is a new concept.
