B-locus genotypes have been defined in Obese strain (OS) chickens that spontaneously develop autoimmune thyroiditis (SAT), and in White Leghorn Cornell C strain (CS) chickens from which the OS was selected. The B-locus influences SAT, and some possible mechanisms are discussed. Thymic abnormalities in OS, as contrasted with CB birds, are also discussed and may play a role in SAT, as may an intrinsic defect in the thyroid gland itself.
