Background: Accumulating studies have reported that there is an association between the Ring finger protein 213 (RNF213) p.R4810K (rs112735431, c.14576G>A) single nucleotide polymorphism and the predisposition of moyamoya disease (MMD), intracranial major artery stenosis/occlusion (ICASO), quasi-moyamoya disease (quasi-MMD), and other vascular diseases. However, to this day, analyses about this association have remained scarce in the literature. We attempted to conduct a meta-analysis to systematically summarize and clarify the issue. Methods: Electronic databases dated up to January 2018 were searched, retrieved, and used. Revman 5.2 software and STATA version 12.0 were used for statistical analysis. The association between RNF213 p.R4810K and MMD, ICASO, and quasi-MMD were assessed by odds ratios and 95% confidence intervals using fixed effects models. Between-study heterogeneity was evaluated by I-squared (12) statistics and sensitivity analysis was performed by omitting 1 study at a time. A funnel plot and Begg's test were used to assess the potential publication bias. Results: The outcomes showed a statistically significant association between RNF213 p.R4810K and MMD, ICASO, and quasi-MMD, especially in the dominant model. Apart from the first 2 diseases, no significant association was identified under the recessive, the homozygote, and the heterozygote models in ICASO. Conclusions: RNF213 p.R4810K was associated with MMD, ICASO, and quasi-MMD in different genetic models. Subgroup analysis indicated highly significantly higher risk in the Japanese patients. However, further well-designed studies with larger sample size and comprehensive data are needed to confirm our findings and provide a profound conclusion.
