Chromosomal assignment of the genes for two major human aldehyde dehydrogenase isozymes, that is, cytosolic aldehyde dehydrogenase-1 (ALDH1) and mitochondrial aldehyde dehydrogenase-2 (ALDH2) were determined. Genomic DNA, isolated from a panel of mouse-human and Chinese hamster-human hybrid cell lines, was digested by restriction endonucleases and subjected to Southern blot hybridization using cDNA probes for ALDH1 and for ALDH2. Based on the distribution pattern of ALDH1 and ALDH2 in cell hybrids, ALDH1 was assigned to the long arm of human chromosome 9 and ALDH2 to chromosome 12.
