Abstract excerpt
PURPOSE: To identify the mutation in the RB1 gene in a Syrian family showing incomplete penetrance of retinoblastoma (RB). METHODS: Genomic DNA was used as a template for the PCR reaction to amplify all exons as well as the promoter region of RB1 gene. These PCR products were screened by conformational sensitive gel electrophoresis and the 331-bp product containing exon 21 showing anomalous migration was...
