Cockayne syndrome is a rare condition which causes short stature, premature aging (progeria), severe photosensitivity, and moderate to severe learning delay.[1] 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.[2]  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.[3] This type is a more severe form in which growth and developmental abnormalities are present at birth.[2] 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.[2] Individuals with type 1 or 2 usually do not survive past childhood, whereas those with type 3 live into adulthood.[1]
