Sažetak:
Fragile X mutation detection by DNA analysis enables accurate diagnosis of the fragile X syndrome. The mutation involves the expansion of CGG repeats in the FMR1 gene and has been primarily detected by the Southern blotting method. In this study we present a novel, efficient and reliable PCR protocol that is more convenient for routine diagnosis of the fragile X syndrome. This method is based on the use of the Expand Long PCR System, which enables the amplification of normal, premutated and full-mutated alleles, and therefore provides complete CGG repeat analysis of the FMR1 gene. Normal alleles were easily detected by ethidium bromide staining of the agarose gels, suggesting that this assay could be used as a screening test for a large number of referrals. The amplified premutations and full mutations were identified by hybridization with a digoxigenin-labeled 5"-(CGG)(5)-3" probe, followed by chemiluminescent detection. The accuracy of our Expand Long PCR protocol was confirmed by Southern blot analysis, illustrating that the Expand Long PCR results concur with those of Southern blotting. In this paper we propose a new strategy for molecular diagnosis of the fragile X syndrome in which our Expand Long PCR assay is used as the first screening test for fragile X mutation detection.
