Knockdown the moyamoya disease susceptibility gene, RNF213, upregulates the expression of basic fibroblast growth factor and matrix metalloproteinase-9 in bone marrow derived mesenchymal stem cells. Neurosurg Rev 2024; 47:246. [PMID: 38811382 DOI: 10.1007/s10143-024-02448-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 04/30/2024] [Accepted: 05/06/2024] [Indexed: 05/31/2024]
Abstract
Moyamoya disease (MMD) is a chronic, progressive cerebrovascular occlusive disease. Ring finger protein 213 (RNF213) is a susceptibility gene of MMD. Previous studies have shown that the expression levels of angiogenic factors increase in MMD patients, but the relationship between the susceptibility gene RNF213 and these angiogenic mediators is still unclear. The aim of the present study was to investigate the pathogenesis of MMD by examining the effect of RNF213 gene knockdown on the expression of matrix metalloproteinase-9 (MMP-9) and basic fibroblast growth factor (bFGF) in rat bone marrow-derived mesenchymal stem cells (rBMSCs). Firstly, 40 patients with MMD and 40 age-matched normal individuals (as the control group) were enrolled in the present study to detect the levels of MMP-9 and bFGF in serum by ELISA. Secondly, Sprague-Dawley male rat BMSCs were isolated and cultured using the whole bone marrow adhesion method, and subsequent phenotypic analysis was performed by flow cytometry. Alizarin red and oil red O staining methods were used to identify osteogenic and adipogenic differentiation, respectively. Finally, third generation rBMSCs were transfected with lentivirus recombinant plasmid to knockout expression of the RNF213 gene. After successful transfection was confirmed by reverse transcription-quantitative PCR and fluorescence imaging, the expression levels of bFGF and MMP-9 mRNA in rBMSCs and the levels of bFGF and MMP-9 protein in the supernatant of the culture medium were detected on the 7th and 14th days after transfection. There was no significant difference in the relative expression level of bFGF among the three groups on the 7th day. For the relative expression level of MMP-9, there were significant differences on the 7th day and 14th day. In addition, there was no statistically significant difference in the expression of bFGF in the supernatant of the RNF213 shRNA group culture medium, while there was a significant difference in the expression level of MMP-9. The knockdown of the RNF213 gene affects the expression of bFGF and MMP-9. However, further studies are needed to determine how they participate in the pathogenesis of MMD. The findings of the present study provide a theoretical basis for clarifying the pathogenesis and clinical treatment of MMD.

Monogenic Causes in Familial Stroke Across Intracerebral Hemorrhage and Ischemic Stroke Subtypes Identified by Whole-Exome Sequencing. Cell Mol Neurobiol 2022:10.1007/s10571-022-01315-3. [PMID: 36580209 DOI: 10.1007/s10571-022-01315-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Accepted: 12/20/2022] [Indexed: 12/30/2022]
Abstract
Whole exome sequencing (WES) has been used to detect rare causative variants in neurological diseases. However, the efficacy of WES in genetic diagnosis of clinically heterogeneous familial stroke remains inconclusive. We prospectively searched for disease-causing variants in unrelated probands with defined familial stroke by candidate gene/hotspot screening and/or WES, depending on stroke subtypes and neuroimaging features at a referral center. The clinical significance of each variant was determined according to the American College of Medical Genetics guidelines. Among 161 probands (mean age at onset 53.2 ± 13.7 years; male 63.4%), 33 participants (20.5%) had been identified with 19 pathogenic/likely pathogenic variants (PVs; WES applied 152/161 = 94.4%). Across subtypes, the highest hit rate (HR) was intracerebral hemorrhage (ICH, 7/18 = 38.9%), particularly with the etiological subtype of structural vasculopathy (4/4 = 100%, PVs in ENG, KRIT1, PKD1, RNF213); followed by ischemic small vessel disease (SVD, 15/48 = 31.3%; PVs in NOTCH3, HTRA1, HBB). In contrast, large artery atherosclerosis (LAA, 4/44 = 9.1%) and cardioembolism (0/11 = 0%) had the lowest HR. NOTCH3 was the most common causative gene (16/161 = 9.9%), presenting with multiple subtypes of SVD (n = 13), ICH (n = 2), or LAA (n = 1). Importantly, we disclosed two previously unreported PVs, KRIT1 p.E379* in a familial cerebral cavernous malformation, and F2 p.F382L in a familial cerebral venous sinus thrombosis. The contribution of monogenic etiologies was particularly high in familial ICH and SVD subtypes in our Taiwanese cohort. Utilizing subtype-guided hotspot screening and/or subsequent WES, we unraveled monogenic causes in 20.5% familial stroke probands, including 1.2% novel PVs. Genetic diagnosis may enable early diagnosis, management and lifestyle modification. Among 161 familial stroke probands, 33 (20.5%) had been identified pathogenic or likely pathogenic monogenic variants related to stroke. The positive hit rate among all subtypes was high in intracerebral hemorrhage (ICH) and ischemic small vessel disease (SVD). Notably, two previously unreported variants, KRIT1 p.E379* in a familial cerebral cavernous malformation and F2 p.F382L in familial cerebral venous sinus thrombosis, were disclosed. CVT cerebral venous thrombosis; HTN Hypertensive subtype; LAA large artery atherosclerosis; SV structural vasculopathy; U Undetermined.

Abstract
OBJECTIVE To investigate potential genetic susceptibility for moyamoya disease (MMD) in an African American family. MATERIALS AND METHODS Neurovascular imaging and analyses of MMD susceptibility genes RNF213 and/or ACTA2 in a young proband with MMD and two first-degree relatives. RESULTS The proband presented with pseudobulbar affect and chorea, then had a right hemispheric ischaemic stroke and rapidly fatal course. One relative had a mild haemorrhagic thalamic stroke and clinically silent ischaemic infarct. Despite evidence of slowly progressive disease, he remained clinically stable. Another relative was neurologically intact with normal cerebrovascular imaging to date. All three have the rare R4131C (p.Arg4131Cys or p.R4131C, c.12391C>T) variant of the RNF213 gene. They are the first Black people and only the 5th family worldwide known to harbour this variant. MMD was confirmed in both of the patients with neurological events. CONCLUSIONS Our report provides compelling evidence that MMD is a clinically complex, heritable genetic disease. It supports the probable pathogenicity of R4131C. Furthermore, it illustrates the wide phenotypic spectrum of R4131C, from asymptomatic carrier to late presenting, mild disease to catastrophic, rapidly fatal childhood disease. To our knowledge, this is also the first report of heritable MMD in a Black family. Finally, this study highlights the importance of racially and ethnically diverse participants in biomedical research.

Abstract
Moyamoya disease (MMD) is a rare cerebrovascular disease characterized by progressive spontaneous bilateral occlusion of the intracranial internal cerebral arteries (ICA) and their major branches with compensatory capillary collaterals resembling a “puff of smoke” (Japanese: Moyamoya) on cerebral angiography. These pathological alterations of the vessels are called Moyamoya arteriopathy or vasculopathy and a further distinction is made between primary and secondary MMD. Clinical presentation depends on age and population, with hemorrhage and ischemic infarcts in particular leading to severe neurological dysfunction or even death. Although the diagnostic suspicion can be posed by MRA or CTA, cerebral angiography is mandatory for diagnostic confirmation. Since no therapy to limit the stenotic lesions or the development of a collateral network is available, the only treatment established so far is surgical revascularization. The pathophysiology still remains unknown. Due to the early age of onset, familial cases and the variable incidence rate between different ethnic groups, the focus was put on genetic aspects early on. Several genetic risk loci as well as individual risk genes have been reported; however, few of them could be replicated in independent series. Linkage studies revealed linkage to the 17q25 locus. Multiple studies on the association of SNPs and MMD have been conducted, mainly focussing on the endothelium, smooth muscle cells, cytokines and growth factors. A variant of the RNF213 gene was shown to be strongly associated with MMD with a founder effect in the East Asian population. Although it is unknown how mutations in the RNF213 gene, encoding for a ubiquitously expressed 591 kDa cytosolic protein, lead to clinical features of MMD, RNF213 has been confirmed as a susceptibility gene in several studies with a gene dosage-dependent clinical phenotype, allowing preventive screening and possibly the development of new therapeutic approaches. This review focuses on the genetic basis of primary MMD only.

Abstract
Intracranial vascular abnormalities rarely are encountered in primary care. Many of the pathologies are occult and prognosis varies widely between inconsequential variants of anatomy to acutely life-threatening conditions. Consequently, there often is a great deal of anxiety associated with any potential diagnosis. This article reviews anatomic intracranial vascular lesions, including vascular malformations (arteriovenous malformations/arteriovenous fistulae and cavernous malformations), structural arteriopathies (aneurysms and moyamoya), and common developmental anomalies of the vasculature. The focus includes a general overview of anatomy, pathology, epidemiology, and key aspects of evaluation for the primary care provider and a review of common questions encountered in practice.

Abstract
Intracranial artery stenosis (ICAS) is the most common cause of ischemic stroke worldwide. RNF213 single nucleotide variant c.14429G > A (p.Arg4810Lys, rs112735431) was recently reported to be associated with ICAS in East Asians. However, the disease susceptibility of other RNF213 variants has not been clarified. This study comprehensively investigated ICAS-associated RNF213 variants in a pool of 168 Japanese ICAS patients and 1,194 control subjects. We found 138 nonsynonymous germline variants by target resequencing of all coding exons in RNF213. Association study between ICAS patients and control subjects revealed that only p.Arg4810Lys had significant association with ICAS (P = 1.5 × 10-28, odds ratio = 29.3, 95% confidence interval 15.31-56.2 [dominant model]). Fourteen of 138 variants were rare variants detected in ICAS patients not harboring p.Arg4810Lys variant. Two of these rare variants (p.Cys118Arg and p.Leu2356Phe) consistent with variants previously reported in moyamoya disease patients characterized by stenosis of intracranial artery and association with RNF213, and three rare variants (p.Ser193Gly, p.Val1817Leu, and p.Asp3329Tyr) were found neither in control subjects and Single Nucleotide Polymorphism Database. The present findings may improve our understanding of the genetic background of intracranial artery stenosis.

Abstract
The ring finger protein 213 gene (RNF213) rs112735431 was significantly associated with intracranial artery stenosis/occlusion disease (ICASO) in Japan and Korea and to a lesser degree in China. We conducted a case-control study to examine the prevalence and correlates of the RNF213 rare variants in Chinese patients with symptomatic ICASO. A total of 503 cases including 390 ischemic stroke patients (ICASO-IS), 113 intracranial hemorrhage patients (ICASO-ICH) and 227 control subjects were recruited. The snapshot technique was used for RNF213 rare variants analysis, including rs112735431, rs148731719, rs37144111 and rs138130613. Moreover, a meta-analysis was performed to explore the relationship between RNF213 variants and ICASO in Asian. In our case-control study, we found that the rs138130613 variant was significantly associated with ICASO-IS (OR = 9.92, 95% CI 1.24-79.19, p = 0.03). The mean age of first ischemic stroke onset of variant carriers was earlier than the noncarriers (51.3 ± 18.0 versus 66.0 ± 12.9 years old, p = 0.02), but the conventional atherosclerotic risk factors and the characteristics of artery stenosis did not differ between them. In addition, the meta-analysis showed significant association between the rs112735431 polymorphism and the ICASO or ICASO-IS, and this variant was found more often in women and young-onset patients in Asia. This study suggests that the RNF213 rs112735431 and rs138130613 are genetic risk variants for ischemic stroke with intracranial artery stenosis/occlusion in China and rs112735431 is also associated with the high risk of ICASO in Asia. Further large-scale investigation of the RNF213 gene will provide new insights into pathogenetic mechanisms of symptomatic ICASO.

Abstract
Moyamoya disease (MMD) is a rare cerebrovascular disorder characterized by occlusion of bilateral internal carotid and intracerebral arteries with the compensatory growth of fragile small vessels. MMD patients develop recurrent infarctions in the basal ganglia and subcortical regions. Symptoms include transient ischemic attack or stroke, seizures, and headaches, which may occur suddenly or in a stepwise progression. Mutations in Ring Finger Protein 213 (RNF213), a Zinc ring finger protein, have been identified in some MMD patients but the etiology of MMD is still largely unknown. To gain insight into the pathophysiology of MMD, we characterized the impact of the RNF213 mutations on plasma protein and RNA profiles. Isobaric tags for relative and absolute quantitation and proximity extension assay were used to characterize the plasma proteome. Next generation sequencing-based small RNAseq was used to analyze the cell-free small RNAs in whole plasma and RNA encapsulated in extracellular vesicles. The changes of miRNAs and proteins identified are associated with signaling processes including angiogenesis and immune activities which may reflect the pathology and progression of MMD.

Abstract
In this report, we present a European family with six individuals affected with Moyamoya disease (MMD). We detected two novel missense variants in the Moyamoya susceptibility gene RNF213, c.12553A>G (p.(Lys4185Glu)) and c.12562G>A (p.(Ala4188Thr)). Cosegregation of the variants with MMD, as well as a previous report of a variant affecting the same amino acid residue in unrelated MMD patients, supports the role of RNF213 in the pathogenesis of MMD.

Vascular tortuosity of the internal carotid artery is related to the RNF213 c.14429G > A variant in moyamoya disease. Sci Rep 2019; 9:8614. [PMID: 31197213 PMCID: PMC6565706 DOI: 10.1038/s41598-019-45141-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2019] [Accepted: 05/31/2019] [Indexed: 12/03/2022] Open
Abstract
Recent studies have implicated RNF213 mutations in the pathogenesis of moyamoya disease (MMD). However, the underlying mechanism of disease development is not fully elucidated. Nonetheless, a possible relationship between vascular morphology and hemodynamics related with MMD has been proposed. Here, we aimed to investigate the relationship between a variant of RNF213 and the morphology of the internal carotid artery (ICA). We enrolled bilateral MMD patients who had undergone genetic testing for RNF213. Patients were divided into mutant and wild-type groups. Six anatomy-specific three-dimensional coordinates were collected using magnetic-resonance angiography. From these, five vectors between two adjacent points and four angles between two adjacent vectors were calculated. The tortuosity was defined as the ratio between the actual and the linear length of the ICAs. Among 58 patients, 44 and 14 belonged to the mutant and wild-type groups, respectively. The tortuosity of ICAs was significantly lower in the mutant group (p = 0.010). The change in blood flow direction was more prominent in the wild-type group (p = 0.002). The tortuosity was significantly lower in MMD patients than normal controls (p < 0.001). Our results indicate that RNF213 could play a role in the lower tortuosity observed in patients with RNF213 mutation.

BMC MEDICAL GENETICS 2019; 20:55. [PMID: 30925911 PMCID: PMC6441181 DOI: 10.1186/s12881-019-0788-9] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/10/2019] [Accepted: 03/18/2019] [Indexed: 12/16/2022]
Abstract
BACKGROUND RNF213 rare variant-p.R4810K (rs112735431) was significantly associated with intracranial artery stenosis/occlusion disease (ICASO) in Japan and Korea and to a lesser degree in China. Considering the allelic heterogeneity, we performed target exome sequencing of RNF213 with the aim to identify the rare variants spectrum and their association with ICASO in a Chinese population and further to explore whether the rare variants carrier patients present specific clinical phenotype. METHODS Target exome sequencing of RNF213 was performed in 250 ICASO patients using FastTarget sequencing technology. Various filtering process were used to select the candidate variants. Control individuals were obtain from 1000 Genome Project (208 Chinese samples) and GeneSky in-house database (1007 samples). Gene-based association analyses were conducted to identify the association between RNF213 rare variants and ICASO. The clinical characteristics of rare variant carriers and non-carriers were compared using Chi-squared test or Fisher's exact test. RESULTS After filtration, 18 rare variants were identified in 39 patients. Gene-based association test showed that rare variants of RNF213 were significantly associated with ICASO (Minor allele frequency < 0.05, WSS p = 4.88 × 10- 10; SKAT p = 9.68 × 10- 6; SKAT-O p = 3.42 × 10- 9). There were no significant clinical characteristic differences other than the diagnosis age which was older in the carriers than the non-carriers (60.5 ± 6.2 vs 57.3 ± 8.9 years old, p = 0.028). CONCLUSION Rare variants of RNF213 are associated with ICASO in Chinese. However, there are limited genetic diagnosis values of the gene due to no specific phenotypic presentation in the carriers and non carrier patients.

Abstract
Background The p.R4810K and other rare variants of ring finger protein 213 gene (RNF213) were illustrated as susceptibility variants for moyamoya (MMD) and non-moyamoya intracranial artery stenosis/occlusion disease (ICASO) recently. However, the effect sizes of p.R4810K were in great discrepancy even in studies of the same ethnic population and firm conclusions of other rare variants have been elusive given the small sample sizes and lack of replication. Thus, we performed this study to quantitatively evaluate whether or to what extent the rare variants of RNF213 contribute to MMD and ICASO in different populations. Methods A systematic search of PubMed, EMBASE, ISI web of science, CNKI, and WANFANG DATA was conducted up to 5 September 2017. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using random- or fixed-effect models based on the between-study heterogeneity. The subgroup analyses were performed by the ethnicity and family history. Sensitivity and publication bias analysis were performed to test the robustness of associations. All the statistical analyses were conduct using STATA 12.0. Results Twenty studies including 2353 MMD cases and 5488 controls and 11 studies including 1778 ICASO cases and 3140 controls were included in this study. Pooled ORs indicated that RNF213 p.R4810K significantly increased MMD and ICASO risk in East Asians with great effect sizes of discrepancy (dominant model: odds ratios 184.04, 109.77, and 31.53 and 10.07, 28.52, and 5.59 for MMD and ICASO, respectively, in Japan, Korea, and China). It significantly increased familial MMD risk in Japan, Korea, and China with 5 ~ 36 times larger effect sizes than that for sporadic ones in each country (dominant model ORs 1802.44, 512.42, 1109.02 and 134.35, 99.82, and 30.52, respectively, for familial and sporadic cases). The effect sizes of RNF213 p.R4810K to sporadic MMD were 3 ~ 4 times larger in Japan and Korea than those in China. RNF213 p.R4810K also increased the ICASO risk in Japan and Korea with 2 ~ 4 times larger effect sizes than that in China (dominant model ORs 10.71, 28.52, and 5.59, respectively). Another two rare variants- p.E4950D and p.A5021V significantly increased MMD risk in Chinese population (dominant model ORs 9.06 and 5.01, respectively). Various other rare variants in RNF213 were identified in Japanese, Chinese, European, and Hispanic American populations without association evidence available yet. Conclusions This meta-analysis shows the critical roles of RNF213 p.R4810K in MMD especially familial MMD and ICASO in Japan, Korea, and China. Except for RNF213 p.R4810K, MMD seems to have more complex determiners in China. Distinct genetic background exists and other environmental or genetic factor(s) may contribute to MMD. Studies focused on delineating the ethnicity-specific factors and pathological role of RNF213 variants in MMD and ICASO are needed.

Abstract
Moyamoya angiopathy (MMA) is a cerebral angiopathy affecting the terminal part of internal carotid arteries. Its prevalence is 10 times higher in Japan and Korea than in Europe. In East Asian countries, moyamoya is strongly associated to the R4810K variant in the RNF213 gene that encodes for a protein containing a RING-finger and two AAA+ domains. This variant has never been detected in Caucasian MMA patients, but several rare RNF213 variants have been reported in Caucasian cases. Using a collapsing test based on exome data from 68 European MMA probands and 573 ethnically matched controls, we showed a significant association between rare missense RNF213 variants and MMA in European patients (odds ratio (OR)=2.24, 95% confidence interval (CI)=(1.19-4.11), P=0.01). Variants specific to cases had higher pathogenicity predictive scores (median of 24.2 in cases versus 9.4 in controls, P=0.029) and preferentially clustered in a C-terminal hotspot encompassing the RING-finger domain of RNF213 (P<10-3). This association was even stronger when restricting the analysis to childhood-onset and familial cases (OR=4.54, 95% CI=(1.80-11.34), P=1.1 × 10-3). All clinically affected relatives who were genotyped were carriers. However, the need for additional factors to develop MMA is strongly suggested by the fact that only 25% of mutation carrier relatives were clinically affected.

Abstract
Purpose Moyamoya disease (MMD) is a rare cerebrovascular disorder characterized by stenosis of the internal carotid arteries with compensatory development of collateral vessels. Although a founder variant of RNF213, p.Arg4810Lys (c.14429G>A, rs112735431), is a major genetic risk factor for MMD in East Asians, the frequency and disease susceptibility of other variants in this gene remain largely unknown. In the present study, we investigated the association of RNF213 variants with MMD in Korean patients and population controls. Methods For all RNF213 variants listed in the Human Gene Mutation Database (HGMD) as disease-causing or likely disease-causing mutations for MMD, genotyping was performed using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Genetic data from 264 adult patients with MMD were analyzed and compared with two control populations comprised of 622 and 1,100 Korean individuals, respectively. Results Among the 30 RNF213 variants that were listed in the HGMD, p.Arg4810Lys was identified in 67.4% (178/264) of patients with MMD and showed a significantly higher allele frequency than in the controls, giving an odds ratio of 63.29 (95% confidence interval, 33.11–120.98) for the 622 controls and 48.55 (95% confidence interval, 31.00–76.03) for the 1100 controls. One additional variant, p.Ala5021Val (c.15062C>T, rs138130613), was identified in 0.8% (2/264) of patients; however, the allele frequencies were not significantly different from those in the controls. Conclusions These results suggest that, in our cohort of Korean patients, the p.Arg4810Lys is the only variant that is strongly associated with MMD among the 30 RNF213 variants listed in the HGMD.

Abstract
OBJECTIVE The aim of this study was to help people comprehensively understand the research advances related to ring finger protein 213 (RNF213) in moyamoya disease (MMD) and to understand the disease at the molecular level to provide a new perspective of the diagnosis of the disease. DATA SOURCES This review was based on data in articles published between 2005 and 2015 that were retrieved from the PubMed database. The search terms included RNF213, MMD, intracranial major artery stenosis /occlusion (ICASO), genotype, phenotype, mutant and variants, and the combinations of these terms. STUDY SELECTION Articles related to MMD and RNF213 were selected for review, and we also reviewed publications related to ICASO. RESULTS RNF213 is not only associated with MMD but also associated with intracranial major artery stenosis. In addition, RNF213 variants exhibit apparent ethnic diversity; specifically, the c.14576G>A variant is mainly detected in Korean, Chinese, and Japanese populations, particularly the latter population. The genotypes of RNF213 correlate with the phenotypes of MMD; for example, the homozygous c.14576G>A variant is associated with early-onset, severe symptoms, and an unfavorable prognosis. Furthermore, the RNF213 c.14576G>A variant should be considered during the diagnosis of MMD because no patients with quasi-MMD have been reported to carry the RNF213 c.14576G>A variant whereas 66 of 78 patients with definite MMD have been found to carry this variant. CONCLUSIONS The growing literature demonstrates that MMD is primarily caused by the synergy of genetic and environmental factors, and unknown genetic modifiers might play roles in the etiology of MMD. Further research should be conducted to clarify the pathogenic mechanism of MMD.

RNF213 rs112735431 polymorphism in intracranial artery steno-occlusive disease and moyamoya disease in Koreans. J Neurol Sci 2017; 375:331-334.

Abstract
BACKGROUND The rs112735431 polymorphism of the RNF213, a susceptibility variant for moyamoya disease (MMD), may be associated with non-MMD intracranial artery steno-occlusive disease of non-MMD type (non-MMD ICAD) in Asian. We investigated whether the rs112735431 polymorphism of the RNF213 affect the development of non-MMD ICAD in Koreans compared to MMD and control group. METHODS We included 31 patients with non-MMD ICAD, 25 patients with MMD, and 100 participants as control group. The rs112735431 polymorphism of the RNF213 was evaluated by polymerase chain reaction amplification of target and detection by restriction fragment length polymorphism analysis. Clinical phenotype was compared between patients with and without the rs112735431 polymorphism in non-MMD ICAD and MMD. RESULTS The rs112735431 polymorphism of the RNF213 was significantly associated with non-MMD ICAD (p=0.001; odds ratio, 14.3; 95% confidence interval, 2.80-73.2) and MMD (p<0.0001; odds ratio, 126.0; 95% confidence interval, 24.2-656.0). The rate of hypertension was more frequent in MMD with the rs112735431 polymorphism than MMD without polymorphism (p=0.010). CONCLUSIONS The rs112735431 polymorphism of the RNF213 is highly associated not only with MMD but also with non-MMD ICAD in Koreans. Also, our study suggests that the rs112735431 polymorphism of the RNF213 may be linked to the hypertension in MMD. Further studies are needed to clarify the relationship between the rs112735431 polymorphism of the RNF213 and hypertension in patients with MMD.

Abstract
Intracranial aneurysms (IAs) are the result of focal weakness in the artery wall and have a complex genetic makeup. To date, genome-wide association and sequencing studies have had limited success in identifying IA risk factors. Distinct populations, such as the French-Canadian (FC) population, have increased IA prevalence. In our study, we used exome sequencing to prioritize risk variants in a discovery cohort of six FC families affected by IA, and the analysis revealed an increased variation burden for ring finger protein 213 (RNF213). We resequenced RNF213 in a larger FC validation cohort, and association tests on further identified variants supported our findings (SKAT-O, p = 0.006). RNF213 belongs to the AAA+ protein family, and two variants (p.Arg2438Cys and p.Ala2826Thr) unique to affected FC individuals were found to have increased ATPase activity, which could lead to increased risk of IA by elevating angiogenic activities. Common SNPs in RNF213 were also extracted from the NeuroX SNP-chip genotype data, comprising 257 FC IA-affected and 1,988 control individuals. We discovered that the non-ancestral allele of rs6565666 was significantly associated with the affected individuals (p = 0.03), and it appeared as though the frequency of the risk allele had changed through genetic drift. Although RNF213 is a risk factor for moyamoya disease in East Asians, we demonstrated that it might also be a risk factor for IA in the FC population. It therefore appears that the function of RNF213 can be differently altered to predispose distinct populations to dissimilar neurovascular conditions, highlighting the importance of a population's background in genetic studies of heterogeneous disease.

Abstract
BACKGROUND Moyamoya disease (MMD) is a chronic, occlusive cerebrovascular disease characterized by bilateral steno-occlusive changes at the terminal portion of the internal carotid arteries and an abnormal vascular network at the base of the brain determining stroke in children. Patients with a similar vasculopathy and associated conditions are affected by the moyamoya syndrome (MMS). Most of the studies focused on MMD were carried out on East-Asian population. Ring Finger 213 (RNF213) has been identified as the strongest susceptibility gene for MMD in East-Asian people. Overall, 74.5% of the East-Asian patients carry the founder variant p.Arg4810Lys of RNF213 never reported in Caucasians. A different genetic landscape among the diverse ethnic populations seems to exist. METHODS We sequenced the coding sequence region of RNF213, TGFB1 and PDGFRB in 21 ethnically homogeneous Italian children with moyamoya; comprehensive sequencing data are available from parents of eight of them. The analyses were carried out by NGS on Thermo-fisher PGM platform. We also performed a comprehensive review of the literature about the variations of these three genes in Caucasian patients. RESULTS Several new variants of RNF213 gene were detected, in particular, two new pathogenic mutations on RNF213 (p.Trp4677Leu and p.Cys4017Ser) were identified in one MMS case and in one MMD case, respectively. Moreover, in a MMS case a new probably causing disease mutation p.Pro1063Thr of PDGFRB was detected. CONCLUSIONS The genetic susceptibility of Asian moyamoya vasculopathy seems to differ from the Caucasian disease. No additional differences seem to exist between MMD and MMS.

Abstract
α-smooth muscle actin, encoded by ACTA2 gene, is an isoform of the
vascular smooth muscle actins, typically expressed in the vascular smooth muscle
cells contributing to vascular motility and contraction. ACTA2 gene mutations
cause a diversity of diffuse vasculopathies such as thoracic aortic aneurysms
and dissections as well as occlusive vascular diseases, including premature
coronary artery disease and ischemic stroke. Dynamics of
differentiation-specific α-smooth muscle actin in arterial smooth muscle
cells and proliferation of the proteins have been well described. Although a
variety of research works have been undertaken in terms of modifications of
α-smooth muscle actin and mutations of ACTA2 gene and myosin, the
underlying mechanisms towards the pathological processes by way of gene
mutations are yet to be clarified. The purpose of the present article is to
describe the phenotypes of α-smooth muscle actin and implications of
ACTA2 mutations in vasculopathies in order to enhance the understanding of
potential mechanisms of aortic and coronary disorders.

A new horizon of moyamoya disease and associated health risks explored through RNF213. Environ Health Prev Med 2015; 21:55-70.

Abstract
The cerebrovascular disorder moyamoya disease (MMD) was first described in 1957 in Japan, and is typically considered to be an Asian-specific disease. However, it is globally recognized as one of the major causes of childhood stroke. Although several monogenic diseases are known to be complicated by Moyamoya angiopathy, the ring finger protein 213 gene (RNF213) was identified as a susceptibility gene for MMD. RNF213 is unusual, because (1) it induces MMD with no other recognizable phenotypes, (2) the RNF213 p.R4810K variant is an Asian founder mutation common to Japanese, Korean and Chinese with carrier rates of 0.5–2 % of the general population but a low penetrance, and (3) it encodes a relatively largest proteins with a dual AAA+ ATPase and E3 Ligase activities. In this review, we focus on the genetics and genetic epidemiology of RNF213, the pathology of RNF213 R4810K, and the molecular functions of RNF213, and also address the public health contributions to current unresolved issues of MMD. We also emphasize the importance of a more updated definition for MMD, of qualified cohort studies based on genetic epidemiology and an awareness of the ethical issues associated with genetic testing of carriers.
