NCIt definition : A rare degenerative genetic disorder with an autosomal recessive pattern of inheritance
that primarily affects the central nervous system. It is caused in some cases by mutations
in the Cockayne syndrome group B gene, CSB/ERCC6, or the xeroderma pigmentosum genes:
XPD/ERCC2, XPG/ERCC5, XPF/ERCC1, which are all involved in the transcription-coupled
nucleotide excision repair pathway of DNA repair. It is currently thought to be part
of the spectrum of disorders within Cockayne syndrome. Clinical signs at birth include
microcephaly, hypotonia, abnormal reflexes and involuntary eye movements. The clinical
prognosis is fatal with survivability beyond 5 years unlikely.;
