Fluorescence in situ hybridization (FISH) mapping of human chromosome 1: Cytogenetic band localization of 71 NotI linking clones on chromosome 1q25
- Univ. of Nebraska Medical Center, Omaha, NE (United States); and others
Seventy-one human chromosome 1q25-qter-specific lambda clones have been isolated from NotI-linking libraries which were constructed using DNA from MCH206.1 somatic cell hybrid cells. These cells contain chromosome 1q25 translocated to chromosome Xp22 as the only human chromosomes in a mouse background. The NotI-linking clones have been mapped to cytogenetic bands. The relative order of ten NotI clones in 1q32 and 1q41 and their relation to known chromosome 1 markers have been also determined. Portions of these ten NotI-linking clones were sequenced. Most of the NotI-linking clones were derived from CpG islands, which are often associated with genes. DNA sequence homologies were searched for these ten NotI-linking clones in sequences available in GeneBank. One of the NotI clones carries sequences identical to TGF-beta 2. The NotI-linking clones described here will be useful for constructing a long-range restriction map of chromosome 1q25-qter and may contribute to the cloning of disease genes.
