The existence of physical anomalies in mongolism is well known, but the existence of "chemical anomalies" in this condition is not so widely recognized.

Simon et al.3 have reported lipoprotein abnormalities in children but not in adults with mongolism.

The purpose of our study has been to investigate serum protein and lipoprotein fractions in mongolism in a wide age spectrum, from infancy to old age, in adequate numbers in various age groups, in both sexes, and with control of as many environmental factors as possible.
