A transcription map covering a 300 kb region around the G6PD gene in the human Xq28 region was constructed by the direct cDNA selection method and the analysis of the resulting region-specific enriched cDNA subllbrary. Seven new genes and two loci of endogenous retrovirus HERV-K were identified. The distribution of the genes across the region is strongly non-uniform and follows the non-uniform distribution of CpG islands in the area. While one of the novel genes was found to be highly homologous to bovine smg p25A GDP-dissociation inhibitor, the remaining genes did not detect any homology to known genes. The analysis of region-specific cDNA subilbraries represents a simple, rapid and efficient tool for the generation of a regional transcription map.
