a 1.8-mb yac contig in xp11.23: identification of cpg islands and physical mapping of ca repeats in a region of high gene density. | the genes araf1, syn1, timp, and pfc are clustered within 70 kb of one another, and, as reported in the accompanying paper (j. knight et al., 1994, genomics 21: 180-187), at least four more genes map within 400 kb: a cluster of krüppel-type zinc finger genes (including znf21, znf41, and znf81) and elk-1, a member of the ets oncogene superfamily. this gene-rich region is of particular interest because of the large number of disease genes mapping to xp11.23: at least three eye diseases (retinitis ... | 1994 | 8088827 |
