How many people have gyrate atrophy

But there have been significant medical advances recently and Conquering Gyrate Atrophy is supporting pioneering research for a cure. Diet There is evidence that when people with gyrate atrophy can reduce the amount of arginine they eat remember arginine turns into ornithine in your body , that can slow the progression of the disease. Some people follow a low protein diet and take supplements which reduces the level of ornithine. This must be done in close consultation with a dietician skilled in metabolic diseases.

Some people find the diet very difficult to follow due to the low levels of protein allowed while others are able to maintain it. Vitamin B6 Some people with gyrate atrophy depending on which mutation of the OAT gene you have can be helped with high doses of vitamin B6. Ask your doctor if this might be right for you. Eye drops Some people with gyrate atrophy experience macular edema which is an accumulation of fluid in the central part of the eye. Prescription eye drops can reduce this fluid in some cases.

If you or a loved one has gyrate atrophy, you may want to join a private Facebook group started by families with gyrate atrophy.

This group includes people from around the world including adults with gyrate atrophy, parents of young children with gyrate atrophy and others affected by the disease. It is intended to be a safe and supportive space for people dealing with all aspects of the disease including managing the diet, dealing with vision loss, and seeking care providers. If you are interested in joining the group, please send a note to info gyrateatrophy. A very important question.

Medical science can move at a fast clip and we believe patients and families have a critical role in influencing research. There are many ways to get involved. Patient registry The first step to finding a cure is developing a list of people with the disease. This is a patient registry that will capture medical information. All the information is anonymous - no one will be able to link your personal information with the information about your disease. Donate Conquering Gyrate Atrophy is an all volunteer organization.

Every donation goes entirely to supporting researchers and research on gyrate atrophy. No donation is too small or too big! Contact us with your questions and ideas at info gyrateatrophy. Here is the database for all clinical trials. Currently the only open trial for gyrate atrophy is the disease registry at My Retina Tracker through Foundation Fighting Blindness. Please consider joining the disease registry if you have gyrate atrophy. Preview the new GARD site.

Conditions with similar signs and symptoms from Orphanet. Careful fundoscopy, fundus autofluorescence images and pointed family history help to delimit autosomal recessive GACR from X-chromosomal choroideremia.

At the slightest suspicion of GACR, serum ornithine levels should be measured to detect hyperornithinemia. Visit the Orphanet disease page for more information. Thank you for visiting nature. You are using a browser version with limited support for CSS.

The case of a year-old woman with gyrate atrophy of the choroid and retina is documented. Additional features in this case, to the authors' knowledge not previously described in gyrate atrophy, are massive cystinuria, massive lysinuria, axial hypermetropia and diabetes. Gyrate atrophy is a rare autosomal recessive degenerative disease of the choroid and retina and is accompanied by defective ornithine metabolism. Simell and Takki 1 demonstrated the association with hyperornithinaemia in The main metabolic features are those of hyperornithinaemia and ornithuria caused by a deficiency of the mitochondrial matrix enzyme, ornithine aminotransferase OAT.

The case of a year-old woman with gyrate atrophy and hyperornithinaemia is documented here. She has been followed up for 12 years and fully investigated. Additional features in this case, to our knowledge not previously described in gyrate atrophy, are massive cystinuria, massive lysinuria, axial hypermetropia and diabetes.
