Hypothesis

Can genetic variations in contactin 4 (CNTN4) contribute to the pathogenesis of autism spectrum disorder (ASD)?

Conclusion

Mutations affecting CNTN4 function may be relevant to the pathogenesis of ASD.

Supporting Evidence

  • The study identified paternally inherited copy number variations in three individuals with ASD.
  • The CNVs affected the CNTN4 gene, which is important for brain development.
  • Molecular analysis revealed that the CNVs resulted from Alu Y mediated unequal recombination.

Takeaway

Some kids with autism have changes in a gene called CNTN4, which helps brain cells connect. These changes might be linked to their autism.

Methodology

The study used array-based comparative genomic hybridization to identify copy number variations in subjects with ASD.

Limitations

The study's findings need further confirmation in larger cohorts.

Participant Demographics

Participants included 92 subjects with ASD from 81 different families, with a mix of ages and backgrounds.
