Design and rationale for examining neuroimaging genetics in ischemic stroke

Abstract: Objective:To describe the design and rationale for the genetic analysis of acute and chronic cerebrovascular neuroimaging phenotypes detected on clinical MRI in patients with acute ischemic stroke (AIS) within the scope of the MRI–GENetics Interface Exploration (MRI-GENIE) study.Methods:MRI-GENIE capitalizes on the existing infrastructure of the Stroke Genetics Network (SiGN). In total, 12 international SiGN sites contributed MRIs of 3,301 patients with AIS. Detailed clinical phenotyping with the web-based Cau… Show more

“…We reviewed all ischemic stroke cases in the neuroimaging repository of the MRI-GENetics Interface Exploration (MRI-GENIE) collaboration [10]. Data were contributed by 12 of the original National Institute of Neurological Disorders and Stroke Genetics Network (NINDS-SiGN) study sites [11].…”

“…Data were contributed by 12 of the original National Institute of Neurological Disorders and Stroke Genetics Network (NINDS-SiGN) study sites [11]. Previous publications provide detailed descriptions of the NINDS-SiGN and MRI-GENIE studies, as well as collection periods and inclusion criteria for each site [10,12].…”

“…3 However, determinants of stroke outcome are poorly understood. 4,5 Recent studies indicate that structural aspects, such as white matter microstructural integrity, are related to functional outcome post-stroke. 6 This reflects the role that structural connectivity, defined by brain regions connected through white matter tracts, has in maintaining brain function and suggests that a disrupted brain network (connectome 7 ) may contribute to the observed symptoms of stroke.…”

“…Even though WMH burden has been linked to both incidence and outcomes of stroke (Kuller et al, 2004), spatial specificity of WMH has not been fully explored. WMH is commonly assessed on axial T2 Fluid Attenuated Inverse Recovery (FLAIR) magnetic resonance (MR) images and total WMH burden can be summarized as WMH volume (WMHv) (Debette and Markus, 2010;Giese et al, 2017;Kuller et al, 2004). Importantly, it has been shown, that WMHv presents an accurate and uniform way of quantifying this phenotype in clinical populations, such as acute ischemic stroke (AIS) patients (Zhang et al, 2015).…”
