| Research Abstract |
Cumulative evidence has shown that abnormal synaptic function represents neuropathogenesis of autism spectrum disorders (ASDs). In this study, we focused on SHANK3 gene, which encodes a synaptic molecule and is identified as a responsible gene for 22q13.3 deletion syndrome. We found novel mutations within CpG islands of SHANK3 gene in ASDs patients, and confirmed the expression of several variants of SHANK3 transcripts from the CpG island region. Further studies show that SHANK3 variants are involved in synaptic dysfunction and autistic behaviours.
