LYNX1 and fragile X syndrome: Expression of LYNX1 was reduced in FXS NPCs at D7, consistent with the decreased expression of LYNX1 (log2FC = −4.36, p = 0.020) in human embryonic stem cell (ESC)-derived NPCs modeling FXS at D12 of differentiation in a previously reported on RNA sequencing analysis (Peteri et al., 2021).
