    Abstract:
    Friedreich's ataxia is an autosomal recessive disease caused by trinucleotide repeat expansion, presenting among other systemic complications, diabetes mellitus. The appearance of motor clumsiness, with running and jumping difficulties in a 6-year-old boy prompted the genetic study of Friedreich's ataxia, confirming his diagnosis. After diagnosis, it was evaluated by Pediatric Cardiology, detecting the presence of non-obstructive hypertrophic cardiomyopathy, and by Pediatric Endocrinology, due to overweight. At 9 years of age, he was diagnosed with diabetes mellitus, a regimen of insulin treatment was initiated. During follow-up, he presented significant neurological deterioration, reaching the use of a wheelchair, which hinders adequate metabolic control. This is a report of a pediatric patient with Friedrich ataxia and diabetes mellitus. La ataxia de Friedreich, de herencia autosómica recesiva causada por una expansión repetida de trinucleótidos se asocia, entre otras complicaciones sistémicas, con diabetes mellitus. La aparición de torpeza motriz, con dificultad en la carrera y el salto en un varón de 6 años motivaron el estudio genético para ataxia de Friedrich y permitieron confirmar el diagnóstico. Tres años más tarde, se diagnosticó diabetes mellitus y se inició el tratamiento con insulina. Durante el seguimiento, presentó un importante deterioro neurológico, con necesidad de usar silla de ruedas, lo que dificultó un adecuado control metabólico. Se presenta el manejo y la evolución de un paciente con ataxia de Friedreich y diabetes mellitus.
