More than 15 ns-cSNPs were detected in five genes: insulin-like growth factor receptor 2 (IGF2R) with 21 ns-cSNPs, REV3-like, catalytic subunit of DNA polymerase zeta (REV3L) with 21 ns-cSNPs, protein kinase, DNA-activated, catalytic polypeptide (PRKDC) with 20 ns-cSNPs, exonuclease 1 (EXO1) with 17 ns-cSNPs, and the excision repair cross-complementing rodent repair deficiency, complementation group 6 (ERCC6) with 16 ns-cSNPs.
If there is no complementation with respect to viability, that is, if we consider lethal distorters belonging to the same "complementation group" ([v.sub.12] = 0), the picture is identical to Figure 4A.
In terms of the cellular NER, excision repair crosscomplementation group 1 (ERCC1) nuclease forms a heterodimer with exicision repair cross-complemenentation group 4 (ERCC4, also known as xeroderma pigmentosum, complementation group F) and accomplishes repair of bulky DNA-platinum adducts (6-8).
