Are gene variations always harmful? |
|
No. Many gene variations have no effect on our body systems or our health and in certain cases these variations can even be beneficial. However, sometimes a variation can make the gene send misinformation or a “garbled” message to the cell. Upon receiving the garbled message, the cell will manufacture a product - such as an enzyme - that doesn't work exactly (or as efficiently) as it should; the variant enzyme may, for example, work faster or more slowly than is best for the body. Combined with an unhealthy diet or lifestyle, such a gene variation may make a person more susceptible to developing certain conditions or in some cases certain illnesses.
