Abstract
Definitive diagnosis to sudden cardiac death (SCD) is often challenging since the postmortem examination on SCD victims could hardly demonstrate an adequate cause of death. It is therefore important to uncover the inherited risk component to SCD. Signal transducer and activators of transcription 5 A (STAT5A) is a member of the STAT family and a transcription factor that is activated by many cell ligands and associated with various cardiovascular processes. In this study, we performed a systematic variant screening on the STAT5A to filter potential functional genetic variations. Based on the screening results, an insertion/deletion polymorphism (rs3833144) in 3'UTR of STAT5A was selected as the candidate variant. A total of 159 SCD cases and 668 SCD matched healthy controls was enrolled to perform a case-control study and evaluate the association between rs3833144 and SCD susceptibility in Chinese populations. Logistic regression analysis showed that the deletion allele of rs3833144 had significantly increased the SCD risk (odds ratio (OR) = 1.54; 95% confidence interval (CI) = 1.18-2.01; P = 0.000955). Further genotype-expression eQTL analysis showed that samples with deletion allele appeared to lower expression of STAT5A, and in silico prediction suggested the local 3 D structure changes of STAT5A mRNA caused by the variant. On the other hand, the bioinformatic analysis presented that promoters of RARA and PTGES3L-AARSD1 could interact with rs3833144, and eQTL analysis showed the higher expression of both genes in samples with deletion allele. Dual-luciferase activity assays also suggested the significant regulatory role of rs3833144 in gene transcription. Our current data thus suggested a possible involvement of rs3833144 to SCD predisposition in Chinese populations and rs3833144 with potential function roles may become a candidate marker for SCD diagnosis and prevention.

Genetic association study of a novel indel polymorphism in HSPA1B with the risk of sudden cardiac death in the Chinese populations. Forensic Sci Int 2020; 318:110637. [PMID: 33309992 DOI: 10.1016/j.forsciint.2020.110637] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2020] [Revised: 10/16/2020] [Accepted: 11/29/2020] [Indexed: 12/12/2022]
Abstract
Sudden cardiac death (SCD) has become a global problem due to its high mortality in the general population. Identification of genetic factors predisposed to SCD is significant since it enables genetic testing that would contribute to molecular diagnosis and risk stratification of SCD. It has been reported that HSPA1B gene mutations might be related with SCD. In this study, based on candidate-gene-based approach and systematic screening strategy, a 5-base pair insertion/deletion (Indel) polymorphism (rs3036297) in the 3'UTR of HSPA1B gene was selected to perform a case-control study aiming to investigate its association with SCD susceptibility in Chinese populations. Logistic regression analysis showed that the insertion allele of rs3036297 was correlated with a comparatively lower risk for SCD [OR=0.58, 95%CI=0.43-0.77, P=1.28×10-4] compared with the deletion allele. Luciferase activity assay indicated that HSPA1B expression could be regulated by rs3036297 through interfering binding with miR-134-5p. Furthermore, analysis of database from Haploreg and GTEx revealed that the rs3036297 variant was involved in potential cis-regulatory element with the promoter of HLA-DRB5 through a long-range interaction and the deletion allele of rs3036297 increased HLA-DRB5 expression. In conclusion, the rs3036297 variant may regulate HSPA1B expression via a mechanism of miRNA binding and HLA-DRB5 expression via a long-range promoter interaction through which contributed to SCD susceptibility. Therefore, rs3036297 would be a potential marker for molecular diagnosis and genetic counseling of SCD.

Abstract
Identifying common genetic variations that are related to sudden cardiac death (SCD) is crucial since it can facilitate the diagnosis and risk stratification of SCD. It has been reported that COX10 mutations might be related with SCD. In this study, we performed a systematic variant screening on the COX10 to filter potential functional genetic variations. Based on the screening results, an insertion/deletion polymorphism (rs397763766) in 3'untranslated regions of COX10 was selected as the candidate variant. We conducted a case-control study to investigate the association between rs397763766 and SCD susceptibility in Chinese populations. Logistic regression analysis showed that the deletion allele of rs397763766 was associated with an increased risk for SCD (odds ratio = 1.61, 95% confidence interval = 1.25-2.07, p = 1.87 × 10-4) susceptibility than insertion allele. Further genotype-phenotype analysis using human cardiac tissue samples suggested that COX10 expression level in genotypes containing deletion allele was higher than that in ins/ins genotype. The results were further reinforced by RNA sequencing data from 1000 Genomes Project. Luciferase activity assay indicated that COX10 expression could be regulated by rs397763766 through interfering binding with miR-15b, thus conferring risk of SCD. In conclusion, the novel rs397763766 polymorphism might be a potential marker for molecular diagnosis and genetic counseling of SCD.

Functional variants in the promoter region of macrophage migration inhibitory factor rs755622 gene (MIF G173C) among patients with heart failure: Association with echocardiographic indices and disease severity. Heart Lung 2020; 50:92-100. [PMID: 32800392 DOI: 10.1016/j.hrtlng.2020.07.015] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 07/09/2020] [Accepted: 07/27/2020] [Indexed: 12/25/2022]
Abstract
BACKGROUND Heart failure (HF) is a serious public health concern resulting in death. An individual predisposition to HF is determined by relationship between genetic and environmental variables. The macrophage migration inhibitory factor (MIF) is a significant mediator that involved in a variety of inflammatory and cardiovascular diseases. To reveal contribution of MIF rs755622 G173C gene variants in the promoter region towards HF pathogenesis and investigate association between recognized genotype and clinical characteristics. PATIENTS AND METHODS We recruited 90 patients with HF, 63 with preserved ejection fraction (HFpEF) and 27 with reduced ejection fraction (HFrEF), and 60 age- and sex- matched controls. MIF rs755622 (G>C) single-nucleotide polymorphism was genotyped by PCR-RFLP method. RESULTS The GG genotype of MIF rs755622 gene polymorphism was more frequent in HF patients than in controls which increased the risk of HF by about 4.25 times (p<0.05). The distribution of the GG, GC and CC genotypes of MIF were 42%, 21% and 0.0% among HFrEF, and 33.3%, 55.6% and 11.1% among HFpEF respectively. Higher frequency of MIF rs755622 G allele among HFrEF (100%) compared to HFpEF (88.9%) (p = 0.007). MIF-GG genotype variant had significantly lower LVEF. In multivariate analysis, MIF-GG genotype was independent risk predictor among HF (OR 4.6). CONCLUSION MIF rs755622 (GG) could be considered as a probable genotypic risk factor for HF, especially in those with HFrEF which increases the possibility that MIF contribute to HF progression. MIF genotype assay may serve as early predictor and help to recognize those at great risk of developing HF.

A common indel polymorphism of the Desmoglein-2 (DSG2) is associated with sudden cardiac death in Chinese populations. Forensic Sci Int 2019; 301:382-387. [PMID: 31220685 DOI: 10.1016/j.forsciint.2019.06.008] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 06/03/2019] [Accepted: 06/05/2019] [Indexed: 11/28/2022]
Abstract
Sudden cardiac death (SCD) is referred to as sudden and unexpected death caused by cardiovascular diseases, in which a person preexisted heart disease or not. Compelling evidence indicates that SCD etiology have been predominantly affected by host genetic factors. However, how genetic variants play roles in the inherited risk component of SCD are still largely unknown. It has been reported that Desmoglein-2 (DSG2) mutations might be related to sudden death. In the present study, we used a candidate gene approach to investigate the associations between rs397729601 (a 2-base pair indel polymorphism) mapping to the 3'UTR of DSG2 with the risk of SCD. It is shown by logistic regression analysis that the risk of SCD has been significantly increased by the deletion allele of rs397729601 [odds ratio (OR)=1.51; 95% confidence interval (CI)=1.12-2.05; P=0.00559]. Additional genotype-phenotype analysis was performed to evaluate the mRNA level, revealing that human myocardium tissues with the deletion allele showed higher expression of DSG2. Dual luciferase activity analysis was conducted in an in vitro reporter gene system, suggesting that DSG2 expression could be regulated by rs397729601 which interrupted the binding of miR-933-3p with DSG2. We concluded that rs397729601 may affect the expression of DSG2 through miR-933-3p regulation, contributing to SCD susceptibility. Thus, rs397729601 may be used as a potential marker for molecular diagnosis and genetic counseling of SCD. Our findings need to be validated through replication and further functional studies.
