Summary

Specific language impairment (SLI), a common childhood disorder, has significant genetic underpinnings. Research points to familial links and specific gene regions, including FOXP2 on chromosome 7, as crucial factors.

Area of Science:

  • Genetics
  • Developmental Pediatrics
  • Linguistics

Context:

  • Specific language impairment (SLI) affects 5-10% of preschool children.
  • SLI is influenced by both environmental and genetic factors.
  • Understanding genetic contributions is key to addressing SLI.

Purpose:

  • To review current data on genetic factors implicated in SLI.
  • To highlight evidence supporting a genetic basis for SLI.
  • To identify specific genes and genomic regions associated with SLI.

Summary:

  • Twin studies and familial case reports first suggested genetic involvement in SLI.
  • Increased relative risk of SLI in close relatives supports genetic links.
  • The FOXP2 gene on chromosome 7 and genomic regions 7q31, 16q, and 19q are strongly linked to SLI.

Impact:

  • Provides a consolidated overview of genetic research in SLI.
  • Informs future genetic studies and potential therapeutic targets.
  • Enhances understanding of the etiology of developmental language disorders.
