Autism spectrum disorders (ASDs) include a variety of developmental brain disorders with clinical findings implicating the dysfunction of the left hemisphere. Here, we generate mice lacking one copy of Sh3rf2, which was detected in ASD patients, to determine whether Sh3rf2 is involved in brain development and whether mutation of SH3RF2 is causative for ASD and the mechanisms linking it to ASD traits. We find that mice with Sh3rf2 haploinsufficiency display significant deficits in social interaction and communication, as well as stereotyped or repetitive behaviors and hyperactivity and seizures. Disturbances in hippocampal dendritic spine development, aberrant composition of glutamatergic receptor subunits, and abnormal excitatory synaptic transmission were detected in heterozygous mutants. Remarkably, these defects are selectively unilateral. Our results support a notion that Sh3rf2 haploinsufficiency is a highly penetrant risk factor for ASD, with disease pathogenesis most likely resulting from deficits in synaptic function in the left hemisphere of the brain.

View all literature mentionsA multi-channel triggering hard-disk recording system designed specifically for bio-acoustics, although it can be used for other audio signals. This software uses real-time spectrographic and spectrum display and posesses a customizable metadata input tool for embedding user-defined data directly into the resulting .wav files. The maximum sampling rate for real-time display and streaming to disk depends on the type of acquisition board and computer performance. These embedded records can later be accessed from SASLab Pro and integrated into another metadata base.
