What causes Coats disease ?
What causes Coats disease? The exact cause of Coats disease is not currently known. However, it is a reported feature of several different genetic syndromes, suggesting there may be a genetic component.[4716] Researchers believe that some cases of Coats disease may be due to somatic mutations in the NDP gene, which lead to deficient levels of a protein called norrin in the developing retina. A somatic mutation in this case is one that is acquired after conception (i.e. it was not inherited from a parent and cannot be passed on to an affected person's children).
