Kearns-Sayre syndrome (KSS) is a rare hereditary disorder that belongs to the group of mitochondrial myopathies. This disorder is characterized by progressive muscle weakness, ophthalmoplegia, cardiac dysfunction, and other systemic symptoms. The key features of the syndrome are external ophthalmoplegic palsy and retinitis pigmentosa, which develop as a result of mitochondrial dysfunction. Mitochondria, as the known energy stations of cells, play a critical role in providing energy for the normal functioning of tissues and organs. The pathogenesis of the syndrome is associated with various mutations in mitochondrial DNA, which leads to progressive disorders in energy metabolism. <\/p>\n
