How genes can cause diseases
Humans have more than 20 000 genes, each carrying out one or a few specific functiosn in the body. One gene instructs the body to digest lactose from milk, another tells the body how to build strong bones and another prevents the bodies cells to begin lultiplying uncontrollably and develop into cancer. As all of these genes combined are the building instructions for our body, a defect in one of these genes can have severe health consequences.
Through decades of genetic research, we know the genetic code of any healthy/functional human gene. We have also identified, that in certain positions on a gene, some individuals may have a different genetic letter from the one you have. We call this hotspots “Genetic Variations” or “Variants” in short. In many cases, studies have been able to show, that having the genetic Letter “G” in the position makes you healthy, but heaving the Letter “A” in the same position disrupts the gene function and causes a disease. Genopedia allows you to view these variants in genes and summarizes all that we know from scientific research, which genetic letters (Genotype) have good or bad consequences on your health or on your traits.
