FOXP1 and apraxia: Although articulation problems have been described in some patients with FOXP1 disruption (Horn et al. 2010), orofacial dyspraxia has not been diagnosed so far (Carr et al. 2010; Hamdan et al. 2010; Horn et al. 2010; O’Roak et al. 2011), neither have any FOXP1 variants been identified in the small DVD patient cohort (Vernes et al. 2009).
