Novel mutation identified in the DDB2 gene in patients with xeroderma pigmentosum group–E

Abstract

Because of the occurrence of early termination codon, truncated nonfunctional proteins or proteins with deleterious loss or gain-of-function activities are synthesized in nonsense mutation. Thus, to avoid the development of pathological lesions, it is important that such patients with nonsense mutation stay away from agents that might cause DNA damage and develop an appropriate lifestyle according to this condition.
