The results of radioiodine uptake studies in 61 children with mongolism and in 68 euthyroid children with mental retardation are presented. No statistically significant difference was found to exist between the uptakes in the 2 groups. This would rule out hypothyroidism, either primary, or secondary to hypopituitarism, as a factor in mongolism.
