Functional and clinical relevance of novel mutations in a large cohort of patients with Cockayne syndrome.
BACKGROUND Cockayne syndrome (CS) is a rare, autosomal recessive multisystem disorder characterised by prenatal or postnatal growth failure, progressive neurological dysfunction, ocular and skeletal abnormalities and premature ageing. About half of the patients with symptoms diagnostic for CS show cutaneous photosensitivity and an abnormal cellular response to UV light due to mutations in eithe...
متن کاملTwo novel mutations in ERCC6 cause Cockayne syndrome B in a Chinese family
Cockayne syndrome (CS) is a rare autosomal recessive disorder characterized principally by progressive growth failure, neurologic abnormality and premature aging. Mutations of excision repair cross‑complementation group 6 (ERCC6) and ERCC8 are predominantly responsible for CS, of which mutation of ERCC6 accounts for approximately two thirds of cases. The current report describes two siblings wi...
متن کاملIdentification of Two Novel ERCC6 Mutations in Old Order Amish with Cockayne Syndrome.
Cockayne syndrome (CS) is a rare autosomal recessive disorder characterized by progressive multisystem degeneration and segmental premature aging. Mutations in the DNA repair gene ERCC6 are responsible for the majority of CS cases reported. In this study, we identified 4 patients presenting with CS from 2 Old Order Amish families. Sequence analysis of the ERCC6 gene revealed 2 novel mutations a...
متن کاملNovel frameshift mutation in the KCNQ1 gene responsible for Jervell and Lange-Nielsen syndrome
Objective(s): Jervell and Lange–Nielsen syndrome is an autosomal recessive disorder caused by mutations in KCNQ1 or KCNE1 genes. The disease is characterized by sensorineural hearing loss and long QT syndrome. Methods: Here we present a 3.5-year-old female patient, an offspring of consanguineous marriage, who had a history of recurrent syncope and congenital sensorineural deafness. The patient ...
متن کاملA Novel Mutation in ERCC8 Gene Causing Cockayne Syndrome
Cockayne syndrome (CS) is a rare autosomal recessive multisystem disorder characterized by impaired neurological and sensory functions, cachectic dwarfism, microcephaly, and photosensitivity. This syndrome shows a variable age of onset and rate of progression, and its phenotypic spectrum include a wide range of severity. Due to the progressive nature of this disorder, diagnosis can be more impo...
