Painful sunburns, and later skin cancer if skin isn’t protected, always result. Seven of the eight known types of XP are categorized as autosomal recessive conditions. [healthline.com]
Other signs and symptoms of xeroderma pigmentosum include eyes that are extremely sensitive to sunlight that may become painful and bloodshot following normal sun exposure, the development of poikilodermas (a UV radiation induce skin lesion characterized [contourderm.com]
This fact actually may have a protective effect against cancer, because patients often naturally avoid UV light as a way of minimizing painful sunburns. The Forgotten Diseases Research Foundation has published an analysis of XP-CS. [forgottendiseases.org]
- Infertility
Y-linked disorders are exceedingly rare but the most well-known examples typically cause infertility. Reproduction in such conditions is only possible through the circumvention of infertility by medical intervention. [en.wikipedia.org]
Gastrointestinal
- Failure to Thrive
Cockayne syndrome is considered in children who have failure to thrive, short stature, abnormal brain imaging, and other features of premature aging. The diagnosis is confirmed with genetic testing. [diseaseinfosearch.org]
Children often suffer from severe failure to thrive and appear cachexic (severely underweight, often to the point of looking wasted). The patient pictured at the right was a 6-year-old girl with XP-CS. [forgottendiseases.org]
Cockayne syndrome should be suspected in a child with postnatal failure to thrive, microcephaly, and two of the other starred (*) clinical findings. Diagnosis is confirmed on genetic testing and the demonstration of mutations in the ERCC genes. [dermnetnz.org]
Two possible exceptions were failure to thrive and sex: 10/10 XP-D patients had failure to thrive, compared to 10/12 XP-G patients. This difference was not statistically significant according to a Fisher’s exact test. [ojrd.biomedcentral.com]
eye disorders and premature aging. [1] [2] [3] Failure to thrive and neurological disorders are criteria for diagnosis, while photosensitivity, hearing loss, eye abnormalities, and cavities are other very common features. [3] Problems with any or [en.wikipedia.org]
Jaw & Teeth
- Dental Caries
Dental caries was present. She could sit but not walk, spoke only bisyllables in a staccato manner. She had photophobia, but could recognize her mother. She had generalized hypotonia, and the deep tendon reflexes were not elicitable. [go.gale.com]
Patients with CS have a combination of sun sensitivity, short stature, severe neurologic abnormalities due to dysmyelination, cataracts, dental caries, a wizened appearance, and a characteristic bird-like facies. [ommbid.mhmedical.com]
Other significant features of CS like deep-set eyes, large and prominent ears, thin nose, progeroid face, deafness, dental caries and sun sensitivity, were also observed in our patients. [scielo.br]
Sensorineural hearing loss and dental caries are common. Skeletal features include microcephaly, kyphosis, flexion contractures of the joints, large hands and feet, and disproportionately long arms and legs. [disorders.eyes.arizona.edu]
Classical Cockayne syndrome patients show (1) growth failure, (2) neurodevelopmental and neurological dysfunction, (3) cutaneous photosensitivity, (4) progressive ocular abnormalities (pigmentary retinopathy, cataract), (5) hearing loss, (6) dental caries [latunisiemedicale.com]
Skin
- Erythema
Sunburns were classified as mild (slight erythema), moderate (marked erythema), or severe (erythema with pain for several days and/or bullae). [jamanetwork.com]
Characteristic findings include mottled skin with erythema, telangiectases, solar elastosis and areas of atrophy as well as the development of numerous premalignancies and malignant tumours. [dermis.net]
Skin findings include photosensitive eruption with erythema and scale, hyperpigmentation, telangiectasia, and subcutaneous lipoatrophy that results in an aged progeric appearance. There is no cancer proneness [4]. [latunisiemedicale.com]
Approximately 50% of affected individuals have acute sun sensitivity from the first few months of life, presenting with severe sunburn and/or persistent erythema which takes weeks to resolve. [orpha.net]
Musculoskeletal
- Small Head
Symptoms of Cockayne syndrome may include height that is below average (short stature), sunlight sensitivity (photosensitivity), difficulty gaining weight (failure to thrive), small head size (microcephaly), hearing loss, eye and bone abnormalities, and [diseaseinfosearch.org]
There are several subtypes of COFS all of which are characterized by progressive neurologic disorder, microcephaly (small head) with intracranial calcifications, prominent noses, large ears, hypotonia, and growth failure. [themedicalbiochemistrypage.org]
In addition to complications involving the skin and eyes, approximately 25-30% of individuals with XP develop neurological abnormalities such as diminished deep tendon reflexes, progressive hearing loss, intellectual disability, small head-size (microcephaly [my46.org]
Microcephaly, a condition where an individual has an abnormally small head, is a common symptom of Cockayne Syndrome. Figure 6. Cataracts, a condition where the lens of the eye becomes clouded and impairs vision, are common in individuals with CS. [beethemgen564s17.weebly.com]
Neurological symptoms of De Sanctis-Cacchione syndrome and some XP subtypes can include: slow or no reflexes poor motor skills small head size (microcephaly) developmental delays muscle rigidity, spasticity, or weakness poor control of bodily movement [healthline.com]

Treatment
Autozygosity mapping and exome sequencing were used to identify the causal mutation, and comet assay on patient fibroblasts before and after niacin treatment to assess its effect on DNA damage. [ncbi.nlm.nih.gov]
Neurological treatment Neurological treatment is restricted due to lack of known treatments as well as fact that many drugs cannot get into to brain or they would cause too many unwanted side effects. [clinuvel.com]
Skin cancer treatment is similar for anyone with skin cancer. Cancerous tissue must be removed promptly. Treatment may include removal of the cancer by freezing, use of an electric needle, or surgery. [xpgrupoluzdeesperanza.org]
While planning treatment by ionizing radiation, detailed counseling is needed regarding the precautions and intensive treatment of possible severe acute radiation reactions during the course of treatment in these patients. [ccij-online.org]

Prognosis
Prognosis The prognosis varies with the severity of the genetic disorder, the success in avoiding UV light and vigilance of screening. [patient.info]
Patients with type II present with a more severe prognosis, whereas patients with type III live into adulthood. Prognosis - Cockayne syndrome Not supplied. [checkorphan.org]
Prognosis There is no cure for XP but sun avoidance and regular follow-up to assess and treat any skin cancers increases life expectancy. For those with no neurological disease and rigorous UV protection, the prognosis is good. [orpha.net]
(Outcomes/Resolutions) Xeroderma Pigmentosa is an inherited genetic disorder with a poor prognosis. [dovemed.com]
Cockayne syndrome II (CS-B) manifests at birth or in infancy, and it has a worse prognosis. [emedicine.medscape.com]
Etiology
Some of CS cases have been reported to be complicated with renal failure, but the genetic background or the etiology of the renal failure has not been reported. [ncbi.nlm.nih.gov]
Etiology Affected individuals have mutations in one of three XP genes: ERCC3 (2q21), ERCC2 (19q13.3), or ERCC5 (13q22-q34). [orpha.net]
Epidemiology
Summary Epidemiology Less than 30 cases have been describedto date. Clinical description The disease manifests during infancy. [orpha.net]
For controls we will compare XP heterozygotes to their non-carrier blood relatives and spouses and to the Surveillance, Epidemiology and End Results (SEER) rates. [clinicaltrials.gov]
Pathophysiology
Molecular studies, which have appeared elsewhere, do not provide full understanding of the pathophysiology of the postnatal growth failure, cachexia, precocious aging, selectivity of tissues affected (such as myelinated axons), and other manifestations [mayoclinic.pure.elsevier.com]
Pathophysiology Cockayne syndrome is an autosomal recessive disorder. A DNA repair defect is a prominent feature of Cockayne syndrome. [emedicine.medscape.com]
