“…Similarly, Fragile X syndrome , caused by an expansion of a CGG repeat in the fragile X gene, exceeds a threshold length at which the protein produced by the gene cannot be detected [ 183 ]. STRs have also been used for the prenatal diagnosis of Down syndrome using amniotic cells [ 184 ], the detection of hemophilia A and B [ 185 , 186 ], the diagnosis of prostate adenocarcinoma in transrectal prostate biopsy specimens [ 187 ], the detection of Duchenne muscular dystrophy [ 188 ] and the duplication screening in Charcot-Marie-Tooth patients [ 189 ]. The requirement of very small amount of DNA, pure or even degraded to some extent, for the analysis of microsatellite markers as well as their adaption to highthroughput systems favored their use in linkage analysis genetics.…”
