Cockayne syndrome is a rare condition which causes short stature, premature aging (progeria), severe photosensitivity, and moderate to severe learning delay. This syndrome also includes failure to thrive in the neonate, microcephaly, and impaired nervous system development. Other symptoms may include hearing loss, tooth decay, and eye and bone abnormalities. Cockayne syndrome type 1 (type A) is sometimes called “classic” Cockayne syndrome and is diagnosed during early childhood. Cockayne syndrome type 2 (type B) is sometimes referred to as the “connatal” type. This type is a more severe form in which growth and developmental abnormalities are present at birth. The third type, Cockayne syndrome type 3 (type C) is a milder form of the disorder. Cockayne syndrome is caused by mutations ineither the ERCC8 (CSA) or ERCC6 (CSB) genes and is inherited in an autosomal recessive pattern. Individuals with type 1 or 2 usually do not survive past childhood, whereas those with type 3 live into adulthood.
