Are gene variations always detrimental?
No. Many gene variations have no outcome on our body systems or our health and in particular cases these variations can even be beneficial. However, sometimes a variation can make the gene send misinformation to the cell. Upon receiving the garbled message, the cell will manufacture a product – such as an enzyme – that doesn’t work precisely (or as competently) 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.
