Assignment of the genes for human beta-glucuronidase and mitochondrial malate dehydrogenase to the region pter leads to q22 of chromosome 7.

In human fibroblast cultures derived from adults, clones of cells with a common chromosome rearrangement have been widely reported. Cells derived from one of these clones have been used in hybridization experiments using mouse cells to localize the genes for beta-glucuronidase and mitochondrial malate dehydrogenase on human chromosome 7. The results of this study indicate that the genes for these isozymes are located on the region pter leads to q22 of human chromosome 7.
