Genetics of language and rhythm

Some children are slow to learn language skills. They may not say words until they are 2 years old. It may also be hard to understand them. They may have Specific Language Impairment (SLI). SLI is a language disorder. It is not associated with any developmental delays or hearing loss. As they get older, children with SLI may have a hard time learning new words. They may also struggle with conversation. Children with SLI have trouble using verbs.The cause of SLI is not known. Scientists think that genetics may play a part. SLI often runs in families. There is also a link between gene changes and rhythm and grammar skill development. So, Researchers at Vanderbilt will use BioVU to look for people with SLI. They will look for known gene changes. They will also look for changes in similar genes. Lastly, they will look for changes in genes linked to musical talent. The results could help us learn what causes SLI. It may also help us learn who might be at risk for SLI. This could help us better treat people with SLI.
