Immune System Disorder
Several autoimmune diseases clearly run in families. Careful studies (for example, those comparing the incidence in identical twins with that in fraternal twins) have shown that the increased incidence of such autoimmune diseases cannot be explained by environmental factors. Rather, it stems from a genetic defect that is passed from one generation to the next. Such disorders include Graves disease, Hashimoto disease, autoimmune gastritis (including pernicious anemia), type I (insulin-dependent) diabetes mellitus, and Addison disease. These diseases are more common in persons who bear particular MHC antigens on their cells. The possession of these antigens does not imply that a person will contract such diseases, only that he or she is more likely to do so. Researchers generally agree that the interaction of many genes is needed before a person develops such autoimmune diseases. For example, type I diabetes is believed to result from at least 14 genes.
Disorders of the immune system
Another interesting feature that appears to relate to the inheritance of autoimmune disorders is gender. Most human autoimmune diseases afflict far more women than men. Women are affected more often than men with most of the better-known disorders, including myasthenia gravis, systemic lupus erythematosis, Graves disease, rheumatoid arthritis, and Hashimoto disease. The reason for this is not fully understood, but researchers think it probably is related to hormonal effects on immune responses.
