Hypothesis
Are there alterations in mRNA expression levels of certain genes in lymphoblastoid cell lines derived from patients with autism spectrum disorder?
Conclusion
The study found that NLGN3 and SHANK3 genes are expressed at lower levels in individuals with autism spectrum disorder compared to healthy controls.
Supporting Evidence
- The mRNA expression levels of NLGN3 and SHANK3 were significantly decreased in individuals with ASD compared to controls.
- Expression levels of NHE9 and AKT1 were not significantly different after correction for multiple tests.
- Reduced expression of NLGN3 and SHANK3 may be related to the pathophysiology of ASD.
Takeaway
This study looked at blood cells from kids with autism and found that two important genes, NLGN3 and SHANK3, were not working as well as in kids without autism.
Methodology
mRNA expression levels of specific genes were measured in lymphoblastoid cells from patients with ASD and healthy controls using real-time quantitative reverse transcriptase polymerase chain reaction assays.
Potential Biases
Potential sample bias due to non-age-matched samples.
Limitations
The sample size may be too small for definitive conclusions, and the study did not perform mutation searches for the examined genes.
Participant Demographics
35 patients with ASD, 27 males and 8 females, aged 3 to 63 years.
Statistical Information
P-Value
0.000036 for SHANK3, 0.00024 for NLGN3
