A 20-month-old infant with "silvery-blond" hair color, widespread confettilike depigmentation of the skin, and mental retardation was found to have, in lymphocytes and fibroblast cultures, increased spontaneous chromosome breaks and breaks induced by both mitomycin and γ-irradiation. The sister chromatid exchange frequency was normal. This child probably represents a new chromosome breakage syndrome. (J Child Neurol 1992;7(Suppl):S79-S82.)
