| pubmed-article:2045104 | pubmed:abstractText | We have used recombinant clones derived from microdissection of the fragile X region to characterize breakpoints around the fragile site at Xq27.3. So far, no microdissection markers derived from Xq28 material have been found, thus allowing a rapid screening for clones surrounding the fragile site by their presence in a somatic cell hybrid containing Xq27.2-Xqter. A total of 43 new DNA markers from Xq27 have been sublocalized within this chromosome band. Of these new DNA markers, 5 lie in an interval defined as containing the fragile X region. The saturation of Xq27 with DNA markers by microdissection demonstrates the power of this technique and provides the resources for generating a complete physical map of the region. | lld:pubmed |
