Summaries for Cockayne Syndrome Type Ii

NIH Rare Diseases : 53 Cockayne syndrome is a rare disease which causes short stature, premature aging (progeria), severe photosensitivity, and moderate to severe learning delay. This syndrome also includes failure to thrive in the newborn, very small head (microcephaly), and impaired nervous system development. Other symptoms may include hearing loss, tooth decay, vision problems, and bone abnormalities. There are three subtypes according to the severity of the disease and the onset of the symptoms:Cockayne syndrome type 1 (type A), sometimes called �??classic�?� or "moderate" Cockayne syndrome, diagnosed during early childhood Cockayne syndrome type 2 (type B), sometimes referred to as the �??severe�?� or "early-onset" type, presenting with growth and developmental abnormalities at birth Cockayne syndrome type 3 (type C), a milder form of the disorder  Cockayne syndrome is caused by mutations in either the ERCC8 (CSA) or ERCC6 (CSB) genes. Inheritance is  autosomal recessive. Type 2 is the most severe and affected people usually do not survive past childhood. Those with type 3 live into middle adulthood. There is no cure yet. Treatment is supportive and may include educational programs for developmental delay, physical therapy, gastrostomy tube placement as needed; medications for spasticity and tremor as needed; use of sunscreens and sunglasses; treatment of hearing loss and cataracts; and other forms of treatment, as needed.

MalaCards based summary : Cockayne Syndrome Type Ii, also known as cockayne syndrome type 2, is related to cerebro-oculo-facio-skeletal syndrome and cockayne syndrome b. An important gene associated with Cockayne Syndrome Type Ii is ERCC6 (ERCC Excision Repair 6, Chromatin Remodeling Factor), and among its related pathways/superpathways are DNA Double-Strand Break Repair and Transcription-Coupled Nucleotide Excision Repair (TC-NER). Affiliated tissues include bone, eye and brain, and related phenotypes are Synthetic lethal with MLN4924 (a NAE inhibitor) and Synthetic lethal with MLN4924 (a NAE inhibitor)

NINDS : 54 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 impaired cognitive development, 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. A small number of individuals with COFS have a mutation in the "ERCC6" gene and are more appropriately diagnosed as having Cockayne Syndrome Type II. Other individuals with COFS may have defects in the xeroderma pigmentosumgenes "XPG" or "XPD." Still others who are diagnosed with COFS have no identifiable genetic defect and are presumably affected because of mutations in a distinct, as-yet-unknown gene. NOTE: This disorder is not the same as Cohen's syndrome (cerebral obesity ocular skeletal syndrome).
