MET and childhood apraxia of speech: Mutations in MET are a risk factor for ASD (Campbell et al., 2006; Jackson et al., 2009; Mukamel et al., 2011; Sousa et al., 2009), and MET is also regulated by the transcription factor FOXP2 (Mukamel et al., 2011), which causes developmental verbal dyspraxia when mutated (Lai et al., 2001).
