Sixteen of 46 variants were polymorphisms with minor allele frequency >1%, and, after conditioning on the p.R4810K genotype, were not associated with MMD.
Biochemical and Functional Characterization of RNF213 (Mysterin) R4810K, a Susceptibility Mutation of Moyamoya Disease, in Angiogenesis In Vitro and In Vivo.
These results confirm that the RNF213 p.Arg4810Lys variant is not uncommon in the general Korean population and provide reference data for the association of this variant and MMD.
These results confirm that alterations in RNF213 predispose patients of diverse ethnicities to MMD, and that the p.R4810K variant predisposes individuals of Asian descent in the United States to MMD.
MDR analysis failed to detect any significant interaction among these five loci in the occurrence of M</span>MD (P>0.05), but the combination of three loci (rs112735431 in RNF213, rs3828610 in PDGFRB, rs3025058 in MMP-3) could have the maximum testing accuracy (57.29%) and cross-validation consistency (10/10).
The coding variant p.R4810K in RNF213 was strongly associated with moyamoya disease in the Japanese (odds ratio: 338.94, p = 1.05 × 10(-100)) and Korean (odds ratio: 135.63, p = 7.59 × 10(-27)) populations, and much less strongly associated in the Chinese population (odds ratio: 14.70, p = 2.63 × 10(-5)).
A case-control study demonstrated strong association of p.R4810K with moyamoya disease in East Asian populations (251 cases and 707 controls) with an odds ratio of 111.8 (P = 10(-119)).
