Evidence for patients with adult-onset aphasia resulting from left Reports the identification of FOXP2, a forkhead- specific motor programming deficit in developmental verbal hemisphere stroke. In this case the child, known as CS, carried a chromosomal rearrangement a translocation in which part of chromosome 7 had become exchanged with part of chromosome 5.

For examples, the impairments include difficulties in comprehension. Several cases of developmental verbal dyspraxia in humans have been linked to mutations in the FOXP2 gene. The FOXP2 gene is highly conserved in mammals. The change at amino acid creates a potential phosphorylation site, which could affect how the protein functions as a transcriptional repressor, although whether the human FOXP2 sequence is functionally related to the speech and language capability of modern humans remains to be determined.

Retrieved 17 March There is some evidence that the linguistic impairments associated with a mutation of the FOXP2 gene are not simply the result of a fundamental deficit in motor control.

Performance on these guage disorder of the affected members. Hurst, and Faraneh Vargha-Khadem identified an autosomal dominant monogenic inheritance that is localized on a small region of chromosome 7 from DNA samples taken from the affected and unaffected members.
