NIH Rare Diseases:43 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. last updated: 5/31/2011

MalaCards: Cockayne Syndrome Type Ii, also known as cerebrooculofacio-skeletal syndrome 1, is related to xeroderma pigmentosum and cockayne syndrome, and has symptoms including cataract/lens opacification, long/large/bulbous nose and broad nasal root. An important gene associated with Cockayne Syndrome Type Ii is ERCC6 (excision repair cross-complementation group 6), and among its related pathways are Cyclophosphamide Pathway, Pharmacodynamics and Fanconi anemia pathway. The compounds thymine glycol and psoralen have been mentioned in the context of this disorder. Affiliated tissues include eye, brain and skin, and related mouse phenotypes are adipose tissue and liver/biliary system.

NINDS:44 Cerebro-oculo-facio-skeletal syndrome (COFS) is a pediatric, genetic, degenerative disorder that involves the brain and the spinal cord. It is characterized by craniofacial and skeletal abnormalities, severely reduced muscle tone, and impairment of reflexes. Symptoms may include large, low-set ears, small eyes, microcephaly (abnormal smallness of the head), micrognathia (abnormal smallness of the jaws), clenched fists, wide-set nipples, vision impairments, involuntary eye movements, and mental retardation, which can be moderate or severe. Respiratory infections are frequent. COFS is diagnosed at birth. Ultrasound technology can detect fetuses with COFS at an early stage of pregnancy, as the fetus moves very little, and some of the abnormalities result, in part, from lack of movement.
