Specific Language Impairment affects hundreds of thousands of British children, and causes them to have difficulties speaking and understanding language. Unlike common speech and language disorders, Specific Language Impairment (SLI), is the impairment of acquisition and language use, which is severe, persistent and often unexpected. SLI is hereditary and is typical of a complex genetic disorder, where certain combinations of functional variants result in less efficient biological processes.
