Abstract
Patients with Friedreich's ataxia (FA) are at an increased risk of developing diabetes mellitus and glucose intolerance. Diabetes usually develops many years after the initial presentation. We report an 8-year-old girl who initially presented with diabetic ketoacidosis and was treated as a case of insulin-dependent diabetes mellitus. Around a year later, she developed gait problems and ataxia. Cardiac involvement was detected on echocardiography. Genetic testing confirmed the diagnosis of FA. FA should be a diagnostic consideration in children presenting with diabetes and neurological issues, even with early presentation of the former. Early occurrence of diabetes and rapid progression of ataxia in this patient needs a better understanding of underlying genetic mechanisms.
