The clinical and phenotypic features of two siblings (a 12 years old girl and her 7 year old brother) with Cockayne syndrome are described. The main problems were mild to moderate mental retardation, dwarfism, clumsy gait, photosensitive skin lesions and progeroid (senile like) appearance. Brain CT - scans revealed symmetrical, well defined areas of calcification mainly located at lenticular nuclei, in both patients. Vie brainstem auditory responses also showed increased hearing thresholds and absolute wave latencies, that were more prominent in the older sister. The older patient had a healthy twin sister with normal mental function and phenotypic appearance.
