Protein mutations link to autism

Date: 24.6.2007 

They have shown one protein increases the excitability of nerve cells, while the other inhibits cell activity. The University of Texas team found that in normal circumstances the proteins balance each other out. But the study, published in Neuron, suggests that in people with autism the balance between the proteins is knocked out of kilter. The findings back the theory that autism involves an imbalance between excitatory and inhibitory connections between nerve cells. The proteins, which serve to physically link nerve cells together, were discovered by the team at the university's Southwestern Medical Center more than a decade ago. However, until the latest study their exact function had been unclear. Lead researcher Dr Ege Kavalali said: "Mutations in these proteins have recently been linked to certain varieties of autism. "This work provides clear insight into how the proteins function. We can never design a therapeutic strategy without knowing what these mutations do."
