Haptoglobin Variations in Newborn Children

Abstract
Haptoglobin types were studied in 352 new-born Swedish children and their mothers. In 145 families serum samples were obtained also from the fathers. In 23% of the new-born children, and 64% of one-week-old children there were determinable haptoglobin patterns. There was no evidence for a relationship between the absence of haptoglobin in the children and the parental phenotypes, nor was there any evidence for the lagging behind of the determinability of Hp 2-2.
