Microsatellites repeat sequences are prone to forming non-canonical DNA structures and mutations. These areas of the genome can undergo expansions and contractions and are responsible for a variety of inherited neurological and neuromuscular disorders. Hairpin structures formed by trinucleotide repeats can lead to replication fork stalling, and fork collapse causing DNA double strand breaks. Various mechanisms are involved in processing microsatellites including mismatch repair, base excision repair, and crossover junction endonuclease cleavage. These processes, which are supposed to protect the genome, could also be the culprits which are causing mutations. In order to test and study this hypothesis, the use …
