A case of hyperornithinemia and gyrate atrophy of choroid and retina has been observed in a 3-year and 9-month-old girl. She presented also mild mental retardation, delayed language development and speech defects. The restriction of protein intake to a minimum of 0.8 g/kg/day induced a significant reduction of plasma ornithine levels. In some of the previous reports of the syndrome, a deficient ornithine-ketoacid transaminase activity has been found in cultured fibroblasts.
