Cockayne synrome (also called Weber-Cockayne syndrome, or Neill-Dingwall Syndrome) is a rare, autosomal recessive disorder characterized by growth failure, impaired development of the nervous system, abnormal sensitivity to sunlight (photosensitivity), and premature aging. Hearing loss and eye abnormalities (pigmentary retinopathy) are other common features, but problems with any or all of the internal organs are possible. It is named after English physician Edward Alfred Cockayne (1880-1956).
