Role of other DNA repair genes in somatic repeat instability in FXD mouse model

Protein	Repair Pathways	Effect	Ref
Polβ	base excision repair/other	↑	[78]
CSB	transcription coupled repair/other	↑	[83]
FAN1	Fanconi anemia/other	↓	[58]
EXO1	MMR/other	↓	[59]
Lig4	non-homologous end-joining	↓	[57]
MRE11	homologous recombination/other	–	[57]

↑: promotes expansion. ↓: prevents expansion; –: no effect.
