A correlation between the expression or absence of human glyoxalase I and chromosome 6 (as well its markers ME1, IPO-B, and PGM3) was observed in man-mouse somatic cell hybrids. This segregation pattern indicates that the GLO gene is situated on chromosome 6.

β¦ Synopsis
Evidence is presented for the assignment of the gene for glyoxylase I to mouse chromosome 17 using mouse x Chinese hamster somatic cell hybrids. GLO I was not expressed concordantly with any known marker enzymes which represented 11 linkage groups. The presence of chromosome 17 and expression of GLO I were concordant in 31/31 clones. GLO I is thus linked to the H-2 histocompatibility locus in the mouse.

Human/hamster hybrid cell cultures were examined for the presence of ARSA and other marker enzymes. Many of these hybrids were also analyzed for human chromosomes. Our results confirm the assignment of ARSA to chromosome 22.
A specific enzyme immunoassay of uroporphyrinogen decarboxylase was developed and applied to the detection of the human enzyme in man-rodent somatic cell hybrids. This method allowed to assign the gene for uroporphyrinogen decarboxylase to human chromosome 1.
