Refined mapping of the three DNA repair genes, ERCC1, ERCC2, and XRCC1, on human chromosome 19

Three DNA repair genes, ERCC1, ERCC2, and XRCC1, have been regionally mapped on human chromosome 19. ERCC2 and XRCC1 have been assigned to bands q13.2----q13.3 by in situ hybridization using fluorescently-labeled cosmid probes. ERCC1 and ERCC2 have been found to be separated by less than 250 kb by large fragment restriction enzyme site mapping.
