title: Chromosomal localization of human glutamate receptor genes.
abstract: The chromosomal localization of human glutamate receptor genes (GluR1-4) has been established using PCR with DNA isolated from mapping panels of Chinese hamster-human hybrid cell lines and high-resolution fluorescent in situ suppression hybridization. This was accomplished with genomic clones containing putative human homologs of rat GluR 1-4 isolated by high-stringency screening of a cosmid library with the rat cDNAs encoding GluR1-4. The locations of GluR1-4, respectively, are 5q32-33, 4q32-33, Xq25-26, and 11q22-23. Evidence implicating glutamatergic synapses in a diversity of physiologic and pathologic processes together with concordance of the chromosomal locales and results of linkage analyses establishes GluR3 and GluR4 as candidate genes for a number of nervous system disorders including the oculocerebral-renal syndrome of Lowe and a form of manic-depressive illness.
