Scientists and geneticists alike have spent years learning more about how to trace the human genome and locate defects. When it comes to the onset of disease, early detection is the key and by tracing the human genome, doctors are no longer forced to wait until the disease has arrived and begun to spread.
One of the main defects that causes humans to become ill are genetic mutations. Since diseases are typically caused by these genetic mutations, the more tracing of the human genome that takes place, the more options that are available to treat them.
Genetic Testing – Tracing Genetic Defects
From there, increased genetic testing is able to be introduced, to help the tracing process. This allows patients to learn more about their likelihood for developing defects and diseases, as well as the likelihood that they will pass on these defective genetics to their children.
In order to trace the human genome for defects, researchers increase their ability to discover how the particular genes have been mutated and how many generations have experienced this mutation. Genes that are more susceptible to disease often go through multiple mutations, which adds further importance to the tracing of the human genome.
Genetic Tracing Process What’s Involved?
The tracing process is often very lengthy, so that scientists have the opportunity to learn more about these multiple mutations. Knowing what human genes are supposed to do is merely half of the battle, while knowing why the gene isn’t doing what it is supposed to do is even more crucial.
A common way to trace the human genome for defects is to use techniques that involve the comparison of DNA from families with a hereditary history of a certain disease with families that do not. Or they can compare the DNA of family members who have experienced disease with other members of the same family who have remained in good health.
When the DNA segments in those who have been affected by disease are the same, scientists are able to mark these specific chromosomes and let researchers know where the defective genes are located. This greatly increases the chances for finding a cure, as well as locating the disease before it has a chance to become full blown.
Human genome tracing is completed with numerous objectives in mind. First and foremost, gene therapy is put in place, so that the genes that are the catalyst for causing cancerous tumours can be eliminated or corrected. This increases the body’s ability to defend itself, by strengthening the immune system.
Cells can also be altered, so that they can successfully withstand higher dosages of chemotherapy. The cancerous cells themselves are also altered, to increase their overall sensitivity to the drugs used during treatment.
While there is still much to be learned about the advantages and potential disadvantages that come with such a bold, new form of fighting disease, early returns have been encouraging. Treating disease and defective genes is all about the amount of information that can be uncovered. In time, humans will be able to keep their defective genes at bay and ensure that they are not passed down to future generations.
Tracing the human genome for defects threatens to change the entire medical landscape, as well as the methods we use for treating deadly diseases. If the defective genes can be altered or singled out, this increases the chances that the onset of disease can be avoided entirely, as well as the opportunity for early detection. In most cases, early detection is the driving factor in overcoming the onset of a disease and tracing the human genome for defects allows patients to seek more favourable outcomes.
