Haptoglobins and transferrins in patients with Down's syndrome

Abstract

Summary 100 institutionalized patients with Down's syndrome were examined for their haptoglobin and transferrin patterns. The haptoglobin patterns in mongols were found to be essentially the same as those in the normal population samples. All the mongols were found to have a transferrin C pattern and therefore they were considered to be no different from the general English population. We wish to thank Prof. L. S. Penrose for his suggestions and assistance; and Dr A. Shapiro and M. Ridler of Harperbury Hospital for their co‐operation.
