Dr Dianne Newbury talks about the contribution of genetics to specific language impairment. Specific Language Impairment (SLI) is a complex genetic disorder in the development of language. Dr Dianne Newbury is looking for the genes that predispose to SLI. Two regions, located on chromosomes 16 and 19, are linked with this disorder. Interactions between several normal genetic variants and environmental factors make certain individuals more vulnerable to language problems. A better understanding of these underlying biological pathways will lead to the development of more accurate identification systems and better therapies.
