TY - JOUR T1 - 700 genes mapped at world workshop Y1 - 1989/07/14 N1 - 10.1001/jama.1989.03430020013002 JO - JAMA SP - 175 EP - 175 VL - 262 IS - 2 N2 - THE OFFICIAL NUMBER of genes tracked to specific sites on human chromosomes grew from 1000 to 1700 one day last month.That Saturday, June 17, marked the closing session of the 10th International Workshop on Human Gene Mapping, a periodic chromosomal housekeeping session in which geneticists from around the world tidy up the genetic map. They usually decide on the proper places for scores of newly discovered genes, rearrange a few others, and even throw some out.Since 1973 they have been gathering every so often to fix each new gene, gene marker, and fragile site located since the last workshop to a particular region of one of the 24 human nuclear chromosomes and the mitochondrial genome. This year when 650 geneticists converged on the Yale campus in New Haven, Conn, on Sunday, June 11, the task before them was more arduous than ever."The number of genes discovered since SN - 0098-7484 M3 - doi: 10.1001/jama.1989.03430020013002 UR - http://dx.doi.org/10.1001/jama.1989.03430020013002 ER -
