J Diabetes Sci Technol 2011;5(4):1025–1026 Case 37 Diabetes in Hereditary Hemochromatosis 1 Donald A. His diabetes had been diagnosed 8 months earlier by fasting glucose and confirmed by HbA1c at a routine visit to his primary care provider. It is important to consider that diabetes presenting in older adults is not always typical type 2 diabetes. In addition, certain medications and other conditions, such as Cushing’s syndrome, pancreatitis, cystic fibrosis, and hereditary hemochromatosis, may cause diabetes through defined mechanisms. These considerations are especially important for those whose phenotype or history is not typical of type 2 diabetes, including individuals who are not obese, individuals with family histories of type 1 diabetes or other autoimmune disorders, or individuals with other comorbidities or laboratory results that might suggest another process or syndrome. The patient was not obese and did not have hypertension or other stigmata of Cushing’s syndrome. He did not use alcohol and had not had any recent weight loss to suggest malabsorption. Because he was of Northern European extraction and was not obese, he was screened for hemochromatosis by determining his transferrin saturation, which was elevated (54%). H63D homozygosity has a milder phenotype and in many cases is not associated with significant iron overload. Mutations in other genes required for normal iron sensing and regulation occur more infrequently and generally cause a more severe phenotype (Table 37. Other morbidities including arthritis, dilated cardiomyopathy, and hypogonadotrophic hypogonadism also occur.
