Alternative Splicing Analysis Reveals Isoforms Associated with FMR1 Repeat Expansion

In a recent publication, scientists from the University of California, Davis, and PacBio reported results from an investigation of alternative splicing associated with a repeat expansion in the gene linked to fragile X syndrome. They used SMRT Sequencing to detect full-length isoforms (Iso-Seq analysis) associated with individuals at risk of FXTAS, an adult-onset neurodegenerative disorder. “Altered expression of the FMR1 splicing variants landscape in premutation carriers” comes from lead author Elizabeth Tseng, senior author Flora Tassone, and collaborators. Previous studies from the Tassone lab had used SMRT Sequencing to detect full-length isoforms in samples from premutation carriers (individuals with more…
