WebJun 9, 2024 · The CGG repeat expansion mutations cause gene methylation and in turn inactivation of the FMR1 gene. This results in a shortage or lack of FMRP and subsequently causes FXS in individuals 4.... WebSep 29, 2024 · The ability of directly sequencing expanded CGG repeats of FMR1 was demonstrated by the single-molecule real-time (SMRT) LRS technology on Pacific Biosciences (PacBio) platform in 2003 . PCR combining PacBio LRS has been applied to detect AGG interruptions, but only in FMR1 premutation carriers (30, 31). WebOct 6, 2016 · Background Fragile X syndrome (FXS), a common cause of intellectual disability and autism, results from the expansion of a CGG-repeat tract in the 5′ untranslated region of the FMR1 gene to >200 repeats. Such expanded alleles, known as full mutation (FM) alleles, are epigenetically silenced in differentiated cells thus resulting in the loss of … john wes townley
