[Assignment of a novel zinc finger gene ZNF191 to human chromosome 18Q12.1 by human/rodent somatic cell hybrid panel and fluorescent in situ hybridization].

A novel human zinc finger gene, ZNF191, was assigned to chromosome 18 by hybridization of human/rodent hybrid cell panel to a full-length cDNA as a probe. Meanwhile, a human genomic DNA lambda/DASH library was screened using this cDNA probe and several positive clones were obtained. Fluorescence in situ hybridization (FISH) was performed by using one of these positive clones, 16-1, as a probe. Thus, the ZNF191 gene was precisely mapped in 18q12. 1. To date, some hereditary diseases and tumors have been found to be associated with this region by analysis of genetic linkage and loss of heterozygosity. Hence, it suggested that the gene ZNF191 can be taken as a candidate gene responsible for those diseases and tumors.
