title: Chromosomal mapping of glutamate dehydrogenase gene sequences to mouse chromosomes 7 and 14.
abstract: Glutamate dehydrogenase (GLUD) plays an important role in mammalian neuronal transmission. In human, GLUD is encoded by a small gene family. To determine whether defects in Glud genes are associated with known neurological mutations in the mouse and to contribute to the comparative mapping of homologous genes in man and mouse, the chromosomal location of genes reactive with a mouse brain GLUD cDNA were determined. Genomic Southern analysis of a well-characterized panel of Chinese hamster x mouse somatic cell hybrids identified two GLUD-reactive loci, one residing on mouse Chromosome 14 and the other on Chromosome 7. Progeny of an intersubspecies backcross were used to map one of these genes, Glud, proximal to Np-1 on Chromosome 14, but no restriction fragment polymorphisms could be identified for the second locus, Glud-2.
