Sažetak
The fragile X syndrome is caused by expansion of the (CGG)n repeat in 5 end of the FMR1 gene. In order to look for linkage disequilibrium between the fragile X locus and its flanking markers, we analyzed the DXS548 and FRAXAC1 microsatellite markers in normal and unrelated fragile X males of Croatian origin. Different distribution of alleles and haplotypes was found between these two samples. A significant increase in frequency of DXS548 allele 2 was found among fragile X patients when compared to normal individuals (31, 3% vs 2.86%). We also noticed a different distribution of FRAXAC1 allele A (18.8% in fragile X group vs. 10.0% in normal population). Haplotype 7-C was the most represented in normal population (57.14%), while haplotypes 2-C, 8-C and 2-A were more frequent in fragile X group (accounted for 43.75% of all fragile X chromosomes and less than 4% of normal population). This difference may suggest the existence of linkage disequlibrium between the two loci and/or selective advantage of this haplotypes among fragile X affected individuals in Croatia.
