Only the association with cardioembolic stroke was robust in sensitivity analyses. There was no association of genetically predicted serum calcium concentrations with all ischemic stroke (per 0.5 mg/dL [about 1 SD] increase in serum calcium: odds ratio 1.03, 95% CI 0.88–1.21) or with any subtype. Conclusions: This study found that genetically higher serum magnesium concentrations are associated with a reduced risk of cardioembolic stroke but found no significant association of genetically higher serum calcium concentrations with any ischemic stroke subtype.]]> Wed 22 Mar 2023 17:11:50 AEDT ]]> A Multi-Layer Functional Genomic Analysis to Understand Noncoding Genetic Variation in Lipids https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50411 Tue 25 Jul 2023 17:30:33 AEST ]]> Multiancestry genome-wide association study of 520,000 subjects identifies 32 loci associated with stroke and stroke subtypes https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47666 Tue 24 Jan 2023 15:47:40 AEDT ]]> Phenome-wide association analysis of LDL-cholesterol lowering genetic variants in PCSK9 https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41899 PCSK9 locus and compared findings with recent trials of pharmacological inhibitors of PCSK9. Methods: Published and individual participant level data (300,000+ participants) were combined to construct a weighted PCSK9 gene-centric score (GS). Seventeen randomized placebo controlled PCSK9 inhibitor trials were included, providing data on 79,578 participants. Results were scaled to a one mmol/L lower LDL-C concentration. Results: The PCSK9 GS (comprising 4 SNPs) associations with plasma lipid and apolipoprotein levels were consistent in direction with treatment effects. The GS odds ratio (OR) for myocardial infarction (MI) was 0.53 (95% CI 0.42; 0.68), compared to a PCSK9 inhibitor effect of 0.90 (95% CI 0.86; 0.93). For ischemic stroke ORs were 0.84 (95% CI 0.57; 1.22) for the GS, compared to 0.85 (95% CI 0.78; 0.93) in the drug trials. ORs with type 2 diabetes mellitus (T2DM) were 1.29 (95% CI 1.11; 1.50) for the GS, as compared to 1.00 (95% CI 0.96; 1.04) for incident T2DM in PCSK9 inhibitor trials. No genetic associations were observed for cancer, heart failure, atrial fibrillation, chronic obstructive pulmonary disease, or Alzheimer’s disease – outcomes for which large-scale trial data were unavailable. Conclusions: Genetic variation at the PCSK9 locus recapitulates the effects of therapeutic inhibition of PCSK9 on major blood lipid fractions and MI. While indicating an increased risk of T2DM, no other possible safety concerns were shown; although precision was moderate.]]> Tue 16 Aug 2022 08:27:58 AEST ]]> The power of genetic diversity in genome-wide association studies of lipids https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48599 Tue 04 Apr 2023 19:22:25 AEST ]]> Implicating genes, pleiotropy, and sexual dimorphism at blood lipid loci through multi-ancestry meta-analysis https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53055 Fri 17 Nov 2023 11:47:02 AEDT ]]>
