Kearns-Sayre syndrome (KSS) is a rare mitochondrial disorder characterized by symptoms such as progressive external ophthalmoplegia, heart block, and other systemic issues. Life expectancy can vary significantly among individuals with KSS, often depending on the severity of the symptoms and associated complications. While some individuals may live into their 20s or 30s, others may have a shorter life span due to the condition's impact on health. Regular medical care and management of symptoms can help improve quality of life and potentially extend longevity.
