Abstract
The genetic polymorphism of transferrin (TF) was studied in 2,167 Japanese individuals and in 448 New Zealanders. The three TF C subtypes were identified, but TF C3 was absent from Japanese populations. In addition, three TF B and six TF D variants were observed, each of which occurred either in Japanese or in New Zealanders. Stepwise removal of N-acetyl-neuraminic acid (NANA) with neuraminidase revealed that the most cathodal variant TF DShinnanyo found in a Japanese family was characterized by having only two NANA residues.
