Gm PHENOTYPES IN AUTOIMMUNE THYROID DISEASE

Abstract

The Gm phenotype Gm f,b or Gm f,n,b was found in all forty patients with Graves' disease studied, contrasted with thirty-five out of forty controls and twenty out of thirty-one patients with thyroiditis. The difference between the two groups with autoimmune thyroid disease was significant. These results suggest that thyroid stimulating antibodies may be allotypically restricted.
