METHIONINE SULFOXIDE REDUCTASE A AND NEUROTRANSMISSION ENZYMES IN AUTISM SPECTRUM DISORDER AND DYSTOCIA RELATED AUTISTICS.

Methionine sulfoxide reductase A (MsrA) is an antioxidant enzyme that repairs the oxidation of methionine residues in proteins and free methionine in autism spectrum disorder (ASD). The present study aimed to assess the level of MsrA and neurotransmission enzymes in ASD individuals. Results confirmed that ASD associated with significant (P<0.
