Risk factorsBy Mayo Clinic staff
Abnormalities in the FOXP2 gene appear to increase the risk of childhood apraxia of speech (CAS) and other speech and language disorders. The FOXP2 gene may be involved in how certain nerves and pathways in the brain develop. Researchers continue to study how abnormalities in the FOXP2 gene may affect motor coordination and speech and language processing in the brain.
Boys are more likely to have CAS than girls. However, girls tend to have a more severe form of CAS.
