Kearns–Sayre syndrome with type 1 diabetes mellitus: A case report

Abstract

Kearns–Sayre syndrome (KSS) is a rare genetic mitochondrial myopathy with a typical onset before 20 years of age. It is a variant of chronic progressive external ophthalmoplegia. It is defined by a characteristic triad of progressive external ophthalmoplegia, pigmentary retinopathy, and cardiac conduction abnormalities. The prevalence rate of KSS is ~1–3 per 100,000 individuals. Here, we report a rare case of an 18 year-old Indian female with KSS and type 1 diabetes mellitus.
