Fragile X syndrome (FXS) is the most common genetically linked cause of intellectual disabilities and autism

Fragile X syndrome (FXS)听is a neurodevelopmental condition occurring due to a CGG trinucleotide expansion in the FMR1 gene. Polymorphisms and variants in large-conductance calcium-activated potassium channels are increasingly linked to intellectual disability and loss of FMR protein causes reduced large-conductance calcium-activated potassium channel activity leading to abnormalities in synapse function.

Using the endo-cannabinoid-like large-conductance calcium-activated potassium channel activator VSN16R, designed in our lab we rescued behavioural deficits such as repetitive behaviour, hippocampal dependent tests of daily living, hyperactivity and memory in a mouse model of fragile X syndrome (Study published in Brain 2021).

VSN16R was designed and synthesised in the Selwood lab at 香港六合彩中特网 by Cristina Visintin and Masahiro Takahiro and originally developed for Multiple Sclerosis. First studies in people with Fragile X are expected in 2023.
