Maguire disease also known as autosomal recessive retinitis pigmentosa (ARRP) is an inherited eye disease that affects the retina. This condition is caused by a mutation in the MFRP gene which is responsible for producing a protein that plays a role in the proper function of the retina. Maguire disease is a rare condition with an estimated prevalence of less than 1 in 1 million people.
The symptoms of Maguire disease typically develop in childhood or adolescence include progressive vision loss night blindness peripheral vision loss decreased ability to see in bright light. Over time the condition can lead to complete blindness. Maguire disease can also cause other eye problems such as cataracts glaucoma.
Maguire disease is caused by a mutation in the MFRP gene which is located on chromosome 11. The MFRP gene provides instructions for making a protein that is important for the function of the retina. The retina is the part of the eye that contains photoreceptor cells which are responsible for converting light into electrical signals that the brain can interpret as vision. The mutation in the MFRP gene leads to the production of an abnormal protein which causes the photoreceptor cells to degenerate eventually die.
Currently there is no cure for Maguire disease. Treatment options are limited focus on managing the symptoms of the condition. This may include the use of low vision aids such as magnifying glasses or telescopes to help improve vision. In some cases surgery may be necessary to treat cataracts or glaucoma.
Research into Maguire disease other forms of retinitis pigmentosa is ongoing. Scientists are working to develop new treatments for these conditions including gene therapy stem cell therapy. Gene therapy involves replacing the defective gene with a healthy copy while stem cell therapy involves using stem cells to replace damaged cells in the retina. While these treatments are still in the early stages of development they offer hope for the future treatment of Maguire disease other inherited eye diseases.
Maguire disease is a rare inherited eye disease that can cause progressive vision loss eventually blindness. While there is currently no cure for this condition research is underway to develop new treatments that may one day offer hope for people with this other forms of retinitis pigmentosa. If you have a family history of Maguire disease or other inherited eye diseases it is important to talk to your doctor about your risk any steps you can take to help protect your vision.
