Abstract
Intracerebral hemorrhage (ICH) is the cerebrovascular disease with the highest disability and mortality rates, causing severe damage to the health of patients and imposing a significant socioeconomic burden. Aging stands as a foremost risk factor for ICH, with a significant escalation in ICH incidence within the elderly demographic, highlighting a close association between ICH and aging. In recent years, with the acceleration of the "aging society" trend, exploring the intricate relationship between aging and ICH has become increasingly urgent and worthy of in-depth attention. We have summarized the characteristics of ICH in the elderly, reviewing how aging influences the onset and development of ICH by examining its etiology and the mechanisms of damage via ICH. Additionally, we explored the potential impacts of ICH on accelerated aging, including its effects on cognitive abilities, quality of life, and lifespan. This review aims to reveal the connection between aging and ICH, providing new ideas and insights for future ICH research.

Abstract
Cerebral small vessel disease (CSVD) encompasses a broad clinical spectrum united by pathology of the small vessels of the brain. CSVD is commonly identified using brain magnetic resonance imaging with well characterized markers including covert infarcts, white matter hyperintensities, enlarged perivascular spaces, and cerebral microbleeds. The pathophysiology of CSVD is complex involving genetic determinants, environmental factors, and their interactions. While the role of vascular risk factors in CSVD is well known and its management is pivotal in mitigating the clinical effects, recent research has identified novel genetic factors involved in CSVD. Delineating genetic determinants can promote the understanding of the disease and suggest effective treatments and preventive measures of CSVD at the individual level. Here we review CSVD focusing on recent advances in the genetics of CSVD. The knowledge gained has advanced understanding of the pathophysiology of CSVD, offered promising early results that may improve subtype identification of small vessel strokes, has led to additional identification of mendelian forms of small vessel strokes, and is getting closer to influencing clinical care through pharmacogenetic studies.

Abstract
Intracerebral hemorrhage (ICH) is a devastating type of stroke, frequently resulting in unfavorable functional outcomes. Up to 15% of stroke patients experience ICH and approximately half of those have a lethal outcome within a year. Considering the huge burden of ICH, timely prevention and optimized treatment strategies are particularly relevant. Nevertheless, ICH management options are quite limited, despite thorough research. More and more trials highlight the importance of the genetic component in the pathogenesis of ICH. Apart from distinct monogenic disorders of familial character, mostly occurring in younger subjects, there are numerous polygenic risk factors, such as hypertension, neurovascular inflammation, disorders of lipid metabolism and coagulation cascade, and small vessel disease. In this paper we describe gene-related ICH types and underlying mechanisms. We also briefly discuss the emerging treatment options and possible clinical relevance of the genetic findings in ICH management. Although existing data seems of more theoretical and scientific value so far, a growing body of evidence, combined with rapidly evolving experimental research, will probably serve clinicians in the future.

Association between Angiotensin Converting Enzyme Insertion/Deletion gene polymorphism with the risk of Hemorrhagic Stroke: A systematic review and Meta-Analysis of 53 studies. Gene 2021; 790:145696. [PMID: 33964377 DOI: 10.1016/j.gene.2021.145696] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Revised: 04/19/2021] [Accepted: 04/30/2021] [Indexed: 01/11/2023]
Abstract
BACKGROUND AND AIMS Hemorrhagic stroke (HS) results in significant mortality and disability worldwide. Angiotensin Converting Enzyme (ACE) is responsible for blood pressure regulation and vascular homeostasis. Our objective was to conduct a comprehensive meta-analysis for ascertaining the association of ACE I/D polymorphism with HS since a number of studies depicted inconclusive evidence. METHODS Literature search was performed till July 10, 2020 in PubMed, EMBASE, Cochrane, Chinese National Knowledge Information and Google Scholar databases with keywords: ('Angiotensin Converting Enzyme' OR 'ACE') AND ('Single Nucleotide polymorphisms' OR 'SNP') AND ('Hemorrhagic stroke or 'HS'). Pooled Odds Ratio (OR) and 95% Confidence Interval (CI) were determined for gene-disease association using either fixed (when I2 < 50%) or random effect (when I2 > 50%) models. Risk of bias in studies was assessed using funnel plots and sensitivity analyses. Statistical analysis was performed using STATA version 13.0 software. RESULTS A total of 53 studies having 5186 HS and 7347 healthy control subjects were included in our meta-analysis. Pooled analyses showed that ACE I/D gene polymorphism had significant association with risk of HS in overall study population [(dominant model: OR = 1.29, 95% CI = 1.12-1.50 & recessive model: OR = 1.79, 95% CI = 1.46-2.20)]. Population subgroup analyses further revealed significant relationship of ACE I/D polymorphism with ICH in Asians (recessive: OR 1.97, 95% CI = 1.57-2.47) but not in Caucasians (recessive: OR 1.02, 95% CI = 0.76-1.36). CONCLUSION This meta-analysis suggests that ACE I/D polymorphism may lead to risk of HS and can be a potential biomarker for HS susceptibility especially in Asian population.

Genetic risk of Spontaneous intracerebral hemorrhage: Systematic review and future directions. J Neurol Sci 2019; 407:116526.

Abstract
BACKGROUND Although highly heritable, few genes have been linked to spontaneous intracerebral hemorrhage (SICH), which does not currently have any evidence-based disease-modifying therapy. Individuals of African ancestry are especially susceptible to SICH, even more so for indigenous Africans. We systematically reviewed the genetic variants associated with SICH and examined opportunities for rapidly advancing SICH genomic research for precision medicine. METHOD We searched the National Human Genome Research Institute-European Bioinformatics Institute (NHGRI-EBI) Genome Wide Association Study (GWAS) catalog and PubMed for original research articles on genetic variants associated with SICH as of 15 June 2019 using the PRISMA guideline. RESULTS Eight hundred and sixty-four articles were identified using pre-specified search criteria, of which 64 met the study inclusion criteria. Among eligible articles, only 9 utilized GWAS approach while the rest were candidate gene studies. Thirty-eight genetic loci were found to be variously associated with the risk of SICH, hematoma volume, functional outcome and mortality, out of which 8 were from GWAS including APOE, CR1, KCNK17, 1q22, CETP, STYK1, COL4A2 and 17p12. None of the studies included indigenous Africans. CONCLUSION Given this limited information on the genetic contributors to SICH, more genomic studies are needed to provide additional insights into the pathophysiology of SICH, and develop targeted preventive and therapeutic strategies. This call for additional investigation of the pathogenesis of SICH is likely to yield more discoveries in the unexplored indigenous African populations which also have a greater predilection.

Abstract
In the recent years there is a growing interest in identification of additional genetic factors of stroke. A growing body of evidence supports the role of genetic factors in determining the risk of both hemorrhagic and ischemic stroke. The article considers the main genes associated with susceptibility to stroke and genetic polymorphisms associated with the disease. Genetic factors, modulating inflammation process, coagulation, lipid metabolism, NO formation, renin-angiotensin-aldosterone system and homeostasis play a significant role in stroke development. A comprehensive analysis of different genes associated with stroke may help to detect individuals with extremely high risk of stroke and implement timely preventive measures to decrease stroke burden.

Abstract
Differences in the incidence of spontaneous intracerebral hemorrhage (ICH) between ethnicities exist, with an estimated 42% of the variance explained by ethnicity itself. Caucasians have a higher proportion of lobar ICH (LICH, 15.4% of all ICH) than do Asians (3.4%). Alterations in the causal factor exposure between countries justify part of the ethnic variance in ICH incidence. One third of ICH risk can be explained by genetic variation; therefore, genetic differences between populations can partly explain the difference in ICH incidence. In this paper, we review the current knowledge of genetic variants associated with ICH in multiple ethnicities. Candidate gene variants reportedly associated with ICH were involved in the potential pathways of hypertension, vessel wall integrity, lipid metabolism, endothelial dysfunction, inflammation, platelet function, and coagulopathy. Furthermore, variations in APOE (in multiple ethnicities), PMF1/SLC25A44 (in European), ACE (in Asian), MTHFR (in multiple ethnicities), TRHDE (in European), and COL4A2 (in European) were the most convincingly associated with ICH. The majority of the associated genes provide small contributions to ICH risk, with few of them being replicated in multiple ethnicities.

Abstract
Intracerebral haemorrhage (ICH) is associated with the greatest morbidity and mortality of all stroke subtypes. Established risk factors for ICH include hypertension, alcohol use, current cigarette smoking, and use of oral anticoagulants and/or antiplatelet agents. Familial aggregation of ICH has been observed, and the heritability of ICH risk has been estimated at 44%. Few genes have been found to be associated with ICH at the population level, and much of the evidence for genetic risk factors for ICH comes from single studies conducted in relatively small and homogenous populations. In this Review, we summarize the current knowledge of genetic variants associated with primary spontaneous ICH. Two variants of the gene encoding apolipoprotein E (APOE) - which also contributes to the pathogenesis of cerebral amyloid angiopathy - are the most likely candidates for variants that increase the risk of ICH. Other promising candidates for risk alleles in ICH include variants of the genes ACE, PMF1/SLC25A44, COL4A2, and MTHFR. Other genetic variants, related to haemostasis, lipid metabolism, inflammation, and the CNS microenvironment, have been linked to ICH in single candidate gene studies. Although evidence for genetic contributions to the risk of ICH exists, we do not yet fully understand how and to what extent this information can be utilized to prevent and treat ICH.

Abstract
The human paraoxonase (PON) gene family includes three members: PON1, PON2, and PON3. PON, which prevents the oxidative modification of lipoproteins, has been implicated as a potential risk factor of the cerebrovascular disease. In this study, we investigated associations between coding region single-nucleotide polymorphisms (cSNPs) of PON1, PON2, and PON3 genes and intracerebral hemorrhage (ICH) in a Korean population. Six cSNPs [rs13306698 and rs662 for PON1; rs12026 and rs7493 for PON2; rs13226149 and rs1053275 for PON3] were genotyped using direct sequencing in 145 ICH patients and 372 control subjects. Of the six cSNPs, rs12026 and rs7493, which were in complete linkage disequilibrium, were associated with ICH in log-additive (GC vs. CC vs. GG, p = 0.0008, OR = 0.53, 95 % CI = 0.36-0.78) and dominant models (GC/CC vs. GG, p = 0.0006, OR = 0.47, 95 % CI = 0.30-0.73). In addition, rs13226149 was associated with ICH in log-additive model (GA vs. AA vs. GG, p = 0.0033, OR = 0.58, 95 % CI = 0.39-0.84). In the allele frequency analysis, the C alleles of rs12026 and rs7493 and the A allele of rs13226149 were also shown to contribute to the decreased risk of ICH (p = 0.001, OR = 0.55, 95 % CI = 0.38-0.80 in rs12026 and rs7493; p = 0.003, OR = 0.58, 95 % CI = 0.40-0.83 in rs13226149). These results suggest that PON genes may be involved in the susceptibility of ICH.
