AbstractBackground:Risk prediction algorithms for coronary heart disease (CHD) are recommended for clinical use. However, their predictive ability remains modest and the inclusion of genetic risk may improve their performance.Methods:QRISK2 was used to assess CHD risk using conventional risk factors (CRFs). The performance of a 19 single nucleotide polymorphism (SNP) gene score (GS) for CHD including variants identified by genome-wide association study and candidate gene studies (weighted using the results from the CARDIoGRAMplusC4D meta-analysis) was assessed using the second Northwick Park Heart Study (NPHSII) of 2775 healthy UK men (284 cases). To improve the GS, five SNPs with weak evidence of an association with CHD were removed and replaced with seven robustly associated SNPs – giving a 21-SNP GS.Results:The weighted 19 SNP GS was associated with lipid traits (p<0.05) and CHD after adjustment for CRFs, (OR=1.31 per standard deviation, p=0.03). Addition of the 19 SNP GS to QRISK2 showed improved discrimination (area under the receiver operator characteristic curve 0.68 vs. 0.70 p=0.02), a positive net reclassification index (0.07, p=0.04) compared to QRISK2 alone and maintained good calibration (p=0.17). The 21-SNP GS was also associated with CHD after adjustment for CRFs (OR=1.39 per standard deviation, 1.42×10Conclusions:The 19-SNP GS is robustly associated with CHD and showed potential clinical utility in the UK population.

Abstract Aims Endothelial dysfunction is a major contributor to the pathogenesis of atherosclerosis. CD40–CD40 ligand interactions confer a pro-inflammatory phenotype to endothelial cells (ECs). Recently, a thymine to cytosine transition (−1T&gt;C) in the Kozak sequence of the CD40 gene (rs1883832) has been associated with coronary heart disease (CHD) in an Asian population. As there are no reports yet regarding its role in other ethnic groups, this study determines if the −1T&gt;C single-nucleotide polymorphism (SNP) could be a risk factor for CHD in Caucasians by performing an association study and elucidates its functional consequence in cultured ECs. Methods and results Molecular and biochemical techniques, cell adhesion assays were used for genotype-stratified human EC characterization. SNP distribution in Caucasians was examined in a hospital-based case–control CHD study and serum levels of soluble CD40 (sCD40) were quantified by ELISA. The SNP in the CD40 gene affected baseline CD40 protein abundance on ECs. There was a genotype-dependent difference in CD40-mediated expression of pro-inflammatory genes. Monocyte adhesion was highest on the surface of cells homozygous for the C allele. Homozygosity for the C allele was associated with significant 2.32-fold higher odds of developing CHD as compared to TT genotype carriers. sCD40 plasma levels were genotype-dependently elevated in CHD patients, indicating a possible prognostic value. Conclusion The C allele of the CD40 SNP provokes a pro-inflammatory EC phenotype, compensated by an enhanced CD40 shedding to neutralize excess CD40 ligand. Homozygosity for the C allele is the cause for a genetic susceptibility to atherosclerosis and its sequelae.

Abstract Background: NKX2.5 is a transcription factor that plays a key role in cardiovascular growth and development. Many independent studies have been conducted to investigate the association between the single nucleotide polymorphism 606G>C (rs3729753) in the coding region of NKX2.5 and congenital heart disease (CHD), although the results were inconsistent. This study aimed to reveal as much as possible the relationship between NKX2.5 single nucleotide polymorphism 606G>C and the risk of congenital heart disease in the Chinese population through meta-analysis.Methods and Results: After retrieving related articles in PubMed, MEDLINE, EMBASE, Web of science, Coherane, China National Knowledge Infrastructure (CNKI), Wanfang DATA, VIP database until Aug 2021, a total of 8 studies were finally included. Then, we merged the qualified research data into allele model, dominant model, recessive model, heterozygous model, homozygous model, additive model respectively. Overall meta-analysis results showed that 606G>C was not associated with congenital heart disease of the Chinese population in any model. Also, subgroup analysis based on congenital heart disease type gave the same negative result. Sensitivity analysis showed that there was no significant correlation after the deletion of each study. The results were negative and the heterogeneity was not significant.Conclusion: Our results show that NKX2-5 single nucleotide polymorphism 606G> C may not lead to the risk of congenital heart disease in Chinese.
