Coordinated Processing of 3′ Slipped (CAG)(n)/(CTG)(n) Hairpins by DNA Polymerases β and δ Preferentially Induces Repeat Expansions

Expansion of CAG/CTG trinucleotide repeats causes certain familial neurological disorders. Hairpin formation in the nascent strand during DNA synthesis is considered a major path for CAG/CTG repeat expansion. However, the underlying mechanism is unclear. We show here that removal or retention of a n...
