Gene found for rare disorder may reveal new pathway in mental retardation

Studying mutations that give rise to a rare genetic disease, genetics researchers have identified a novel biological pathway that may have a broader role during human development, potentially in cases of mental retardation and autism. An international team of researchers identified...
