Single choroideremia gene in nonmammalian vertebrates explains early embryonic lethality of the zebrafish model of choroideremia.
PURPOSE Mutations of the CHM gene underlie the X-linked chorioretinal degeneration choroideremia (CHM). The affected gene product, Rab Escort Protein (REP)1, mediates the posttranslational prenyl modification of Rab GTPases. In patients with CHM, the related REP2 partially compensates for the loss of function of REP1. The objective of this investigation was to study the natural history of disea...
متن کاملMolecular analysis of the choroideremia gene related clinical findings in two families with choroideremia
PURPOSE To investigate the choroideremia (CHM) gene in two families with CHM and to characterize the related clinical features. METHODS Two families underwent complete ophthalmic examinations and three males were diagnosed with CHM. Genomic DNA was extracted from the leukocytes of peripheral blood collected from the two families and from 100 unrelated control subjects from the same population...
متن کاملIsolation of a candidate cDNA for the gene causing retinal degeneration in the rd mouse.
The inherited retinal degeneration of the rd mouse results in the exclusive loss of one cell type, the photoreceptors. We took advantage of this visual-cell loss to devise a strategy for the isolation of photoreceptor-specific cDNAs based on the use of subtractive and differential hybridizations. The resulting pool of photoreceptor-specific cDNAs was screened for a candidate cDNA for the rd gen...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Cloning and characterization of the human choroideremia gene.
Positional cloning has previously resulted in the identification of a gene which is disrupted by deletions in patients with the classic choroideremia (CHM) phenotype. More subtle mutations had been identified in 4 exons of the 3' portion but not elsewhere in the CHM gene. We have now isolated and characterized the complete open reading frame of the CHM gene and determined its exon-intron struct...
