"CRY-1 was expressed in 94% of the CLL patients at diagnosis. The median CRY-1 relative gene expression level (0.006) stratified patients into high and low expression groups. Forty of 100 (40%) CLL patients showed high CRY-1 54/100 (54%) showed low CRY-1 and 6/100 (6%) had undetectable CRY-1 gene expression."xsd:string
