A significance level of P<0.0015 was used, adjusted for the effective number of independent SNPs in the region using the Galwey method. Results: We found no association of any common variants in NOTCH3 (including rs10404382, rs1043994, rs10423702, and rs1043997) with lacunar stroke or white matter hyperintensity volume. We repeated our analysis stratified for hypertension but again found no association. Conclusions: Our study does not support a role for common NOTCH3 variation in the risk of sporadic small-vessel disease.]]> Tue 21 Jul 2020 09:43:47 AEST ]]> Association of MTHFR C677T genotype with ischemic stroke is confined to cerebral small vessel disease subtype https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24521 Thu 04 Nov 2021 10:38:38 AEDT ]]> Genetic overlap between diagnostic subtypes of ischemic stroke https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27245 g=0.96, SE=0.47, P=9x10−4) and profile scores (rg=0.72; 95% confidence interval, 0.52–0.93). Between LAA and cardioembolism and SVD and cardioembolism, correlation was moderate using linear mixed models but not significantly different from zero for profile scoring. Joint meta-analysis of LAA and SVD identified strong association (P=1x10−7) for single nucleotide polymorphisms near the opioid receptor μ1 (OPRM1) gene. Conclusions: Our results suggest that LAA and SVD, which have been hitherto treated as genetically distinct, may share a substantial genetic component. Combined analyses of LAA and SVD may increase power to identify small-effect alleles influencing shared pathophysiological processes.]]> Sat 24 Mar 2018 07:29:11 AEDT ]]>
