Autism is a neurodevelopmental disorder characterized by abnormal reciprocal social interactions, communication deficits and repetitive behaviors with restricted interests. A previous quantitative proteomic profiling study demonstrated that microtubule-associated stable tubule only polypeptide (STOP; also known as MAP6) protein was significant reduced in the cerebral cortex from BTBR mouse model of autism compared to the C57BL/6J mice. In the present study, the result showed that the concentration of STOP/MAP6 protein was significantly reduced in the plasma of autistic subjects than that in healthy controls. Finally, a possible mechanism of STOP/MAP6 protein in the pathogenesis of autism was proposed.
