HL‐A8: A Genetic Link with Thyrotoxicosis*

Abstract
The incidence of HL-A8 was significantly increased in 64 Caucasian patients with thyrotoxicosis compared with 700 Australian blood donors (42% versus 24%). No significant correlation was observed between HL-A8 and autoantibodies to thyroid components in thyrotoxic patients; thus the association of HL-A8 must be either with the disease itself, or possibly with immune responses not tested for this study.
