	'''''FOXP2''''' is a [[gene~~]] which codes~~ for ~~a [[~~protein~~]] needed~~ for [[speech]] and [[language]].		==Overview==
			'''FOXP2''' is a gene that encodes a transcription factor belonging to the forkhead box (FOX) family of proteins. It is located on chromosome 7 in humans and is known for its role in the development of speech and language. The FOXP2 protein is involved in the regulation of gene expression, influencing the development of neural circuits that are critical for speech and language.

			The FOXP2 gene is expressed in several tissues, including the brain, lungs, and heart. In the brain, it is particularly active in regions associated with motor control and learning, such as the [[basal ganglia]] and [[cerebellum]]. FOXP2 is thought to play a crucial role in the development of neural pathways that facilitate the coordination of complex motor sequences required for speech.

			Mutations in the FOXP2 gene have been linked to a rare speech and language disorder known as developmental verbal dyspraxia (DVD). Individuals with this condition have difficulty with the precise movements required for speech, leading to problems with articulation and phonological processing. Studies of families with DVD have shown that a single mutation in FOXP2 can lead to significant impairments in speech and language.

	''FOXP2'' is ~~popularly dubbed~~ the "language gene", but ~~this is only partly correct since~~ there are ~~other genes involved~~ in ~~language development.<ref>{{cite web\|last1=Harpaz\|first1=Yehouda\|title=Language gene found\|url=http://~~human~~-brain.org/language-gene.html\|website=human-brain.org\|accessdate=31 October 2014}}</ref> It directly regulates a number~~ of other ~~genes, including ''[[CNTNAP2]]'', ''[[CTBP1]]'', and ''[[SRPX2]]''~~.~~<ref name="pmid17999357">{{cite journal \| vauthors = Spiteri E, Konopka G, Coppola G, Bomar J, Oldham M, Ou J, Vernes SC, Fisher SE, Ren B, Geschwind DH \| title = Identification of~~ the ~~transcriptional targets~~ of ~~FOXP2~~, a ~~gene linked to speech and language,~~ in ~~developing~~ human brain \| journal = Am.

			FOXP2 is often cited in discussions of the evolution of language. Comparative studies have shown that the FOXP2 gene is highly conserved across species, but there are two amino acid changes in the human version of the protein that are not present in other primates. These changes are thought to have occurred after the divergence of humans and chimpanzees, suggesting a possible role in the development of human language capabilities.

			Research on FOXP2 has expanded our understanding of the genetic basis of language and speech. Animal models, such as mice and songbirds, have been used to study the effects of FOXP2 on vocalization and learning. These studies have demonstrated that FOXP2 is involved in the neural plasticity required for learning complex vocalizations.

	== ~~References~~ ==		==Related Genes==
	~~{{reflist}}~~		FOXP2 is part of a larger family of forkhead box transcription factors, which includes other genes such as [[FOXP1]] and [[FOXP3]]. These genes share structural similarities and are involved in various developmental processes. FOXP1, for example, is also expressed in the brain and has been implicated in cognitive development and autism spectrum disorders.
