Greig syndrome: Analysis of the GL13 gene
- Institut fuer Humangenetik, Marburg (Germany); and others
Disruption of the zinc finger gene GL13 by translocation events has been implicated as the cause for cephalopolysyndactyly syndrome (GCPS) in several patients. To characterize this genomic region on human chromosome 7p13, we have isolated a YAC contig of more than 1000 kb including the GL13 gene. About 550 kb from this area were subdivided into a cosmid contig with a two- to ten-fold clone coverage. In this region the cloned GL13 cDNA appears to correspond to at least 14 exons spread over a distance of 280 kb. A CpG island defined by two NotI sites and several BssHII and KspI sites is located in a genomic fragment covering the most proximal exon of the cloned GL13 cDNA. Further upstream, five segments conserved between man and mouse were found. In the mouse this region has been characterized as the transgene integration site resulting in the add phenotype. Both the CpG islands and the conserved regions are likely candidates to search for GL13 promoter and control elements. Intron-exon boundaries and breakpoints of the translocation events within the gene region of patients were identified and characterized.
