To assess synaptic function in these mice, we recorded sEPSCs in hippocampal neurons from the three groups of mice (WT mice injected with sgCON, mice exposed to CRS and injected with ANXA2 sgRNA, and HDAC9 OE mice injected with ANXA2 sgRNA) (Fig. 5N). The gene discussed is ANXA2; the disease is congenital rubella syndrome.
