1 FOXP 2 : A gene of linguistic importance
نویسندگان
چکیده
The gene FOXP2 was discovered to be mutated in members of a family possessing a severe language disorder. Originally some researchers believed that this gene was responsible for grammar and called it the “language gene”. After further study of the family, researchers determined that the gene itself was not generally responsible for grammar but that it may be responsible for the development of structures required for spoken language. The present paper suggests that FOXP2 was played a role in the emergence of spoken language during human evolution. This is supported by evidence from human and nonhuman primates and the study of the gene itself. Proposed accounts of how FOXP2 may be related to the emergence of language are given. Furthermore, the present paper hypothesizes that FoxP2 may be causally related to the “critical period” for language acquisition. This hypothesis is supported by evidence from vocal-learning birds, specifically that the levels of the FoxP2 protein vary depending on whether the birds are learning new songs during that time. Furthermore, a very brief discussion of how FOXP2 may be related to symptoms of schizophrenia is included in order to provide a comprehensive account of the gene’s relationship to language. Finally, discussed are the ethical issues surrounding the study of FoxP2’s relationship to the critical period for language acquisition.

The Role of the FOXP Family of Transcription Factors in ASD
Autism spectrum disorders (ASD) is a neurodevelopmental disease with complex genetics; however, the genes that are responsible for this disease still remain mostly unknown. Here, we focus on the FOXP family of transcription factors as there is emerging evidence strongly linking these genes to ASD and other genes implicated in ASD. The FOXP family of genes includes three genes expressed in the c...

متن کاملThe RNA binding protein HuR determines the differential translation of autism-associated FoxP subfamily members in the developing neocortex
Forkhead-box domain (Fox) containing family members are known to play a role in neocorticogenesis and have also been associated with disorders on the autism spectrum. Here we show that a single RNA-binding protein, Hu antigen R (HuR), dictates translation specificity of bound mRNAs and is sufficient to define distinct Foxp-characterized subpopulations of neocortical projection neurons. Furtherm...
متن کاملAlternative Splicing and Gene Duplication in the Evolution of the FoxP Gene Subfamily
The FoxP gene subfamily of transcription factors is defined by its characteristic 110 amino acid long DNA-binding forkhead domain and plays essential roles in vertebrate biology. Its four members, FoxP1-P4, have been extensively characterized functionally. FoxP1, FoxP2, and FoxP4 are involved in lung, heart, gut, and central nervous system (CNS) development. FoxP3 is necessary and sufficient fo...
