Four of these are novel associations at the genome-wide level (rs72934505 [NBEAL1], p 2.2 x 10^-8; rs941898 [EVL], p 4.0 x 10^-8; rs962888 [C1QL1], p 1.1 x 10^-8; rs9515201 [COL4A2], p 6.9 x 10^-9). Conclusions: Genetic associations with WMHV are shared in otherwise healthy individuals and patients with stroke, indicating common genetic susceptibility in cerebral small vessel disease.]]> Wed 15 Dec 2021 16:08:50 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:16959 -7), with independent replication in a second population (p = 0.0048, OR(95% CI) = 1.18(1.05–1.32); meta-analysis p = 2.6×10^-8). The nearby gene, MMP12, was significantly over expressed in carotid plaques compared to atherosclerosis-free control arteries (p = 1.2×10^-15; fold change = 335.6). Permutation analyses demonstrated improved significance for associations when accounting for age-at-onset in all four stroke phenotypes (p<0.001). Our results show that a covariate-informed design, by adjusting for age-at-onset of stroke, can detect variants not identified by conventional GWAS.]]> Wed 11 Apr 2018 17:21:31 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:20390 Wed 11 Apr 2018 16:32:40 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27705 0.9 between SNPs). Although SNPs associated with deep intracerebral hemorrhage did not reach our significance threshold for association with lacunar ischemic stroke (lead SNP OR 1.10, 95% CI 1.03-1.18, p = 0.0073), and with white matter hyperintensity volume in symptomatic ischemic stroke patients (lead SNP OR 1.07, 95% CI 1.01-1.13, p = 0.016), the direction of association was the same. There was no convincing evidence of association with white matter hyperintensities in population-based studies or with non-small vessel disease cerebrovascular phenotypes. Conclusions: Our results indicate an association between common variation in the COL4A2 gene and symptomatic small vessel disease, particularly deep intracerebral hemorrhage. These findings merit replication studies, including in ethnic groups of non-European ancestry.]]> Tue 21 Jul 2020 09:43:56 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:19050 2-fold increased risk of IS compared with subjects in the lowest quintile. Addition of the combined GRS to a simple model based on sex significantly improved the prediction of IS in the combined clinic-based samples but not in the population-based studies, and there was no significant improvement in net reclassification. Conclusions - A multilocus GRS based on common variants for established cardiovascular risk factors was significantly associated with IS both in clinic-based samples and in the general population. However, the improvement in clinical risk prediction was found to be small.]]> Sat 24 Mar 2018 08:05:17 AEDT ]]>
