Fragile X syndrome (FXS) is a neurodevelopmental disorder caused by the selective loss of the expression of the Fmr1 gene. Key symptoms in FXS include intellectual impairment and abnormal anxiety-related behaviors. Fmr1 knockout (KO) mice exhibited reduced anxiety on two behavioral tests as well as a blunted corticosterone response to acute stress. https://safeersappliancers.shop/product-category/rangemaster-professional-plus-60-prop60ngfss-c-60cm-gas-cooker-with-variable-gas/
