Hypothesis
SLC25A12 may confer risk for quantitative RRB traits in ASDs.
Conclusion
The study confirmed an association between SLC25A12 and RRB traits in ASDs, but the direction of the association differed from previous findings.
Supporting Evidence
- The A alleles of rs2056202 and rs2292813 were positively associated with RRB traits in both samples.
- Significant associations were found between specific SNPs and RBS-R scores.
- The study utilized a large sample size to enhance the reliability of findings.
Takeaway
This study looked at a gene related to autism and found that certain genetic variations are linked to repetitive behaviors in kids with autism.
Methodology
Linear regression analyses were conducted on RBS-R scores in two samples: UIC-UF (179 individuals) and SSC (720 families).
Potential Biases
The study may be affected by genetic and phenotypic heterogeneity across different samples.
Limitations
The study did not find evidence for transmission disequilibrium in the SSC sample, indicating potential genetic heterogeneity.
Participant Demographics
The UIC-UF sample included 179 individuals (75 male, 13 female) with a mean age of 8.3 years; the SSC sample included 720 children (620 male, 100 female) with a mean age of 6.9 years.
