摘要：

Cockayne syndrome (CS) is a rare recessive disorder characterized by a number of developmental abnormalities and premature aging. Two complementation groups (A and B) have been identified so far in CS cases. Defective transcription-coupled nucleotide excision repair is the hallmark of these patients, but in recent years evidence has been presented for a possible defect in the base excision repair pathway that removes oxidized bases. Recent results indicate that both A and B complementation groups are involved but the phenotypical consequences of this flaw remain undetermined. (C) 2007 Elsevier Inc. All rights reserved.
