title: [A case of chorea-acanthocytosis associated with low glycohemoglobin A1c].
abstract: We reported the first case of chorea-acanthocytosis associated with low glycohemoglobin A1c. Fasting blood sugar, daily profile of blood sugar, serum fructosamine and 75 g glucose tolerance test were all within normal limits. While abnormal hemoglobins were not detected, red blood cell half-life was sharply reduced to 13.4 days. These findings suggest that the low glycohemoglobin A1c in this case is highly ascribable to the reduction of red blood cell half-life rather than to continuous hypoglycemia. However, we can not rule out that the abnormalities of red blood cell membrane, suggested factors in this disease, may be related to the low glycohemoglobin A1c value. Further investigations on chorea-acanthocytosis cases with normal red blood cell half-life are necessary in order to elucidate whether an abnormal glycohemoglobin A1c value is a specific indication regarding this disease.
