Towards isolation of the gene for X-linked retinitis pigmentosa (RP3)
Abstract
Until recently the region of interest containing the gene for X-linked retinitis pigmentosa (RP3) was thought to lie between CYBB (Xp21.1) and the proximal end of the deletion in patient BB (JBBprox). This region was thought to span 100-150 kb. Here we present new mapping data to show that the distance between the 5{prime} (most proximal) end of CYBB and JBBprox is only 50 kb. Recently Roux et al. (1994) have described the isolation of a gene within this region but this showed no disease-associated changes. Further evidence from mapping the deletion in patient NF (who suffered from McLead`s syndrome and CGD but not RP) and from linkage analysis of our RP3 families with a new dinucleotide repeat suggests that the gene must extend proximally from JBBprox. In order to extend the region of search we have constructed a YAC contig spanning 800 kb to OTC. We are continuing our search for the RP3 gene using a variety of strategies including exon trapping and cDNA enrichment as well as direct screening of cDNA libraries with subclones from this region.
