  • Title: [DNA repair in xeroderma pigmentosum].
    Author: Traupe H, Happle R, Kim MA.
    Journal: Fortschr Med; 1981 Feb 19; 99(7):212-4. PubMed ID: 7216102.
    Abstract:
    DNA-repair of two patients affected with xeroderma pigmentosum was evaluated in lymphocytes after UV-exposure by mitotic index, sister chromatid exchange (SCE) and nucleoid sedimentation. The first patient showed no increase in SCE-rate and a sedimentation profile typical of repair deficient cells. In the second patient an increase in SCE-rate and a considerable, but delayed DNA-repair activity in nucleoid sedimentation was found indicating 2 genetically different defects of DNA-repair. In the second patient a defect of postreplication repair is assumed.
