Cockayne Syndrome is a genetic disorder characterized by growth failure, premature aging, and sensitivity to sunlight. There are two primary types of Cockayne Syndrome: Type I (classical) and Type II (severe). Mutations in the ERCC8 gene are one of the primary causes of this syndrome. Individuals with ERCC8 mutations often show symptoms early in childhood, including developmental delays, microcephaly, and photosensitivity.
