FOXP2 (forkhead box P2) was the first gene characterized in which a mutation affects human speech and language abilities. Locus: 7q31

Differential parent-of-origin expression of FOXP2 in human speech development.


Mutations in FOXP2 cause developmental verbal dyspraxia (DVD).

- specific language impairment (12721956, 15877281)

  • FOXP2 is the first gene to have been implicated in a developmental communication disorder.
  • A heterozygous missense mutation in FOXP2 causes problems in sequencing muscle movements required for articulating speech (developmental verbal dyspraxia), accompanied by wider deficits in linguistic and grammatical processing.
