ROBO1 is involved in core trait underpinning language acquisition, DCDC2 encodes a doublecortin domain-containing family member and is linked to dyslexia, and FOXP2 encodes a member of the forkhead/winged-helix (FOX) family of transcription factors and is required for the proper development of speech and language.
