Genetics is the area of science that studies biological inheritance, i.e: the process by which progenitors transmit their traits and features to their biological descendants.
DNA is the molecule that contains the genes: the necessary instructions for life, and that make each living organism a unique being. Genes are small pieces of DNA that contain the units of genetic information. In humans, these genes are grouped into the 23 chromosomes that make up their entire genome.
In 2003, with the publication of the first complete sequence of the human genome, the era of genomics begins and the research on genetic background diseases undergoes a remarkable boost.
Genetics (plus the environment that surrounds us) is what define the differences that make us unique beings. The study of certain genes or groups of them allows us to know our specific risk or predisposition to develop certain pathologies with a genetic component. This, we’ll be able to act, as far as possible, in delaying the appearance or minimizing the risk of suffering them.
Yes. Depending on what is requested, the study or genetic test can identify changes in chromosomes, in specific genes or groups of clinically relevant genes.
The results can confirm or rule out a clinical diagnosis or determine the predisposition to develop genetic diseases. With this information, personal or family risks can be known and a specialist can establish a treatment and specific preventive measures for each person.
