This is an Observational Study of children under the age of 11 diagnosed with Cockayne Syndrome to assess the natural progression of Cockayne Syndrome disease, with special attention to hearing and physical changes in length or height, weight, head circumference, and arm span during standard treatment.
The primary analytical objective is to determine the rate of linear growth over a 6-month period in children < 2 years of age and over a 12-month period in children ≥ 2 years of age.
Observational Model: Cohort

RATIONALE: Genetic studies may help in understanding the genetic processes involved in the development of some types of cancer and may lead to both earlier detection and prevention of tumo...
This study is to compare the exposure of orally administered Prodarsan to the intravenous dosed Osmitrol (10% solution) in Cockayne Syndrome (CS) patients. Also the pharmacokinetics of sin...
Cockayne syndrome (CS) is related to defective DNA transcription and/or repair and belongs to the family of Nucleotide Excision Repair. It is an autosomal recessive multisystemic disorder ...
The aim of this study is to assess the frequency of metabolic syndrome in Down syndrome patients because the prevalence of diabetes mellitus and obesity is higher in individuals with Down ...
To evaluate the prevalence of metabolic syndrome in HIV-infected patients with previous evaluation of lipodystrophy syndrome, according to the severity of fat accumulation and antiretrovir...
Retarded growth and neurodegeneration are hallmarks of the premature aging disease Cockayne syndrome (CS). Cockayne syndrome proteins take part in the key step of ribosomal biogenesis, transcription o...
Cockayne syndrome (CS) is a severe disorder with no effective treatment. The Cockayne syndrome group B (CSB) gene is one gene responsible for CS and also causes UV sensitive syndrome (UVS), a disorder...
Cockayne Syndrome (CS) is a rare, autosomal recessive disorder characterized by a spectrum of phenotypic abnormalities, including progressive sensorineural hearing loss (SNHL) that involves both perip...
Cockayne Syndrome (CS) is a rare autosomal recessive disorder, which leads to neurodegeneration, growth failure and premature aging. Most of the cases are due to mutations in the ERCC6 gene, which enc...
Progeroid syndrome is a group of disorders characterized by the early onset of diseases that are associated with aging. Best known examples are Werner syndrome, which is adult onset and results from d...
A syndrome characterized by multiple system abnormalities including DWARFISM; PHOTOSENSITIVITY DISORDERS; PREMATURE AGING; and HEARING LOSS. It is caused by mutations of a number of autosomal recessive genes encoding proteins that involve transcriptional-coupled DNA REPAIR processes. Cockayne syndrome is classified by the severity and age of onset. Type I (classical; CSA) is early childhood onset in the second year of life; type II (congenital; CSB) is early onset at birth with severe symptoms; type III (xeroderma pigmentosum; XP) is late childhood onset with mild symptoms.
Condition with a variable constellation of phenotypes due to deletion polymorphisms at chromosome location 22q11. It encompasses several syndromes with overlapping abnormalities including the DIGEORGE SYNDROME, VELOCARDIOFACIAL SYNDROME, and CONOTRUNCAL AMOMALY FACE SYNDROME. In addition, variable developmental problems and schizoid features are also associated with this syndrome. (From BMC Med Genet. 2009 Feb 25;10:16) Not all deletions at 22q11 result in the 22q11deletion syndrome.
Rare congenital disorder with multiple anomalies including: characteristic dysmorphic craniofacial features, musculoskeletal abnormalities, neurocognitive delay, and high prevalence of cancer. Germline mutations in H-Ras protein can cause Costello syndrome. Costello syndrome shows early phenotypic overlap with other disorders that involve MAP KINASE SIGNALING SYSTEM (e.g., NOONAN SYNDROME and cardiofaciocutaneous syndrome).
An autosomal dominant aneurysm with multisystem abnormalities caused by increased TGF-BETA signaling due to mutations in type I or II of TGF-BETA RECEPTOR. Additional craniofacial features include CLEFT PALATE; CRANIOSYNOSTOSIS; HYPERTELORISM; or bifid uvula. Phenotypes closely resemble MARFAN SYNDROME; Marfanoid craniosynostosis syndrome (Shprintzen-Goldberg syndrome); and EHLERS-DANLOS SYNDROME.
Birth defect that results in a partial or complete absence of the CORPUS CALLOSUM. It may be isolated or a part of a syndrome (e.g., AICARDI'S SYNDROME; ACROCALLOSAL SYNDROME; ANDERMANN SYNDROME; and HOLOPROSENCEPHALY). Clinical manifestations include neuromotor skill impairment and INTELLECTUAL DISABILITY of variable severity.
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous mat...
