Assignment of the gene encoding DNA ligase I to human chromosome 19q13.2–13.3

The gene encoding DNA ligase I has been mapped on human chromosome 19 by analysis of rodent-human somatic cell hybrids informative for this chromosome and by two-color fluorescence in situ hybridization. The DNA ligase I gene ( LIG1 ) is localized to 19q13.2–13.3 and is distal to ERCC1 , the most telomeric of three DNA repair genes on this chromosome.
