Effects of repeat expansion sequence on transcription. Repeat expansion sequences can perturb transcription by a epigenetic silencing, b inducing or facilitating bidirectional transcription, c reduced transcription kinetics, or d generating transcripts that can potentially be processed into small RNAs that could guide degradation or silencing of various complementary RNAs, including the xtrRNA itself
