To date, over four thousand genetic diseases have been discovered due to defects in a single gene ("How many genetic diseases are there?"). These disorders are inevitable because they are determined at the moment of conception. Since there are no preventive measures for such diseases, the most that doctors can do is prescribe courses of action for treatment or possible cures. Unfortunately, no treatments and/or cures have been found for every disease. Researchers, for example, are looking for the defective gene for retinitis pigmentosa, a genetic eye disease, to determine an appropriate cure. Funding support is critical to the success of this type of research. With the recent increase in technological knowledge, several new theories have emerged about the treatment of retinitis pigmentosa and other genetic disorders. Retinitis pigmentosa can be inherited from a dominant or recessive gene, from an X-linked chromosome, or have an unknown cause. This disease causes problems with vision in low light or darkness and loss of side or peripheral vision. The time required for these effects to manifest depends on the individual suffering from the disorder (“Retinitis Pigmentosa”). These permanent changes occur due to the inactivity of retinal cells (“Retinitis Pigmentosa”), as well as the death of rod and cone photoreceptor cells in the eye (Komeima). It is possible that some people with RP also develop cataracts. Even if the cataract can be removed, the patient will continue to have this disease after surgery, with some vision restored (“Retinitis Pigmentosa”). The simplest theory for alleviating the symptoms of Retinitis Pigmentosa is to add some supplements to your diet. The studies are currently “i...... half of the work ......
