What causes Coats disease?

The exact cause of Coats disease is not currently known. However, because it has been associated with different genetic syndromes, it has been thought to have a genetic component.[1] It has been suggested that some cases of Coats disease may be due to somatic mutations in the NDP gene, which may result in the deficiency of a protein called norrin in the developing retina.[2] A somatic mutation in this case is one that is acquired after an individual's conception (i.e. it was not inherited from a parent and cannot be passed on to an affected individual's children).
