Scientists have learned how to determine the nature of the inherited gene

Genetics in recent decades has become an integral part of medicine. Determination of the genotype of the child still in the womb can give accurate information about the presence or absence of certain pathologies. Many couples around the world before conception attend genetic counseling, in order to anticipate the possible risks associated with childbirth.

On the eve of scientists at the University of California in San Diego announced that it is now possible to determine the nature of the inherited gene in a child. That is, through a series of analyses of genetics will be able to establish who each gene was inherited from the mother or from the father, reported in the journal Nature Biotechnology.

This technique will allow you to set more accurate diagnoses and to determine the risk of development of pathologies and child. This discovery, says Bing Ren, scientists at the University of California, can turn approaches in personalized medicine.

It is known that all the functions and structure of the human body is determined by its genotype, i.e. the set of chromosomes and genes. Only two sex chromosomes have the same structure to all healthy people, while others are individual and determine the most characteristic of the man. Previously, scientists could not establish where certain inherited the trait from his father or from the mother, but the new technology makes it possible to obtain this information.

The method allows to diagnose a person's susceptibility to certain diseases. Often genetic changes lead to increased risk of prostate cancer. Localization of mutations in the chromosomes also plays an important role in genetic diagnosis. Scientists believe that a uniform distribution of mutations on chromosomes allows you to activate compensatory mechanisms that protect the body from gene expression changes.

In addition, this method allows to accurately determine whether a donor organ for transplantation to the patient. It has been possible and the analysis of the migration of the population by genetic studies.
