Effect of Lithium in Patients With Autism Spectrum Disorder and Phelan-McDermid Syndrome (SHANK3 Haploinsufficiency)

Summary

There is currently no treatment for the body symptoms of Autism Spectrum Disorders (ASD). However, basic research suggests that some forms of ASD may be alleviated, even in the adult stage. The genes involved in ASDs particularly impact synaptic homeostasis. Specific clinical trials in patients with synaptic mutations need to be carried out. In this spirit, patients with deleterious mutations in SHANK3 represent a paradigm. The induced pluripotent stem cells (iPSc) carrying SHANK3 mutations and derived in neurons, can be used for high-throughput screening of pharmacological substances and allow the identification of compounds that can restore the expression level of SHANK3. The objective of this proposed project is to test one of the compounds identified by research on these iPSc as a novel treatment for social communication deficit in patients with deleterious mutations in SHANK3. Its effect on the symptoms of the social deficit could represent a new perspective for other forms of idiopathic autism.
