BackgroundRecent studies have shown that Ras-like without CAAX2 (RIT2) polymorphism is a susceptible factor for Parkinson's disease (PD) and autism spectrum disorder (ASD). SNP rs12456492 and rs16976358 show the emerging evidence of increased risk of PD and ASD, respectively. A meta-analysis examining the relationship between rs12456492 and PD was reported, but the association between rs16976358 and ASD has not been investigated.MethodsWe searched literature from the databases PubMed, Embase, Google Scholar, ScienceDirect, EBSCOhost, OVID, Web of Science, and Wiley up to February 2021. Three studies including 1160 ASD cases and 1367 controls were eventually enrolled in the meta-analysis based on strict inclusion and exclusion criteria.ResultsAll genetics models indicate a significant association between rs16976358 polymorphism and ASD susceptibility (C vs. T: p = 0.001; CC vs. TT: p = 0.001; CT vs. TT: p = 0.009; CC+CT vs. TT: p = 0.001; CC vs. CT+TT: p = 0.001; TT+CC vs. CT: p = 0.013). The results of sensitivity analysis and publication bias of Begg's and Egger's tests were stable in the models of allele (C vs. T), codominant (CC vs. TT), dominant (CC+CT vs. TT), and recessive (CC vs. CT+TT).ConclusionsOur meta-analysis exhibits that the allele C, CC, and CT genotyping of rs16976358 suggest the risk for ASD, but additional studies using a large sample size and ethnically diverse populations need to be included in the future.
