The homologous gene RBFOX1 has been implicated in several neurodevelopmental disorders, including Rolandic Epilepsy (Lal et al.2013) and Autism Spectrum Disorder (Voineagu et al.2011), and is a downstream target of FOXP2, a transcription factor implicated in monogenic speech and language disorders (Ayub et al.2013). This evidence concerns the gene RBFOX1 and Rolandic epilepsy.
