This "bomb" increases the risk of birth of children with serious illnesses, reports the News. com. au. As shown by recent studies, defective sperm cells containing harmful mutations and spontaneous, may, like a cancer, actively proliferate. Over time, this will result in the birth of sick children.

This discovery was made in the course of the study Apert syndrome, which affects the development of the skull and limbs. And, as a rule, detect the syndrome in children with unaffected parents. Although the syndrome is associated with a particular mutation in the FGFR2 gene, the main problem in spontaneous mutations fathers.

This mutation also causes the sperm to make extra copies of itself, according to mood Materials Meddaily site As a result, the aging of the growing number of sperm, as well as the magnitude of the problem. A similar mechanism may be and other diseases, said Professor Anne Gorieli University of Oxford. A striking example - dwarfism. Scientists have developed a technology that allows you to highlight specific problem areas and to carry out a detailed genetic analysis. Experts successfully identified mutations associated with dangerous diseases, in 13 of the 14 analyzed eggs.
