  • Meta-analyses of genome-wide association studies identify novel loci influencing Japanese white matter hyperintensities. - Journal of human genetics (2026) · Asanomi Y, Mitsumori R, Yamakawa A, Morizono T, Shigemizu D, Niida S, Sakurai T, Ozaki K · PubMed 41554961

    White matter hyperintensities (WMH) are common findings on brain magnetic resonance imaging (MRI) in older adults and are associated with an increased risk of dementia and stroke. Although large-scale European genome-wide association studies (GWAS) have identified more than 20 loci associated with WMH, the genetic architecture of WMH in Asian populations has not been fully elucidated. Here, we conducted a GWAS comprising 1001 Japanese individuals from the National Center for Geriatrics and Gerontology (NCGG) Biobank, followed by a meta-analysis with GWAS data from 9479 individuals in the Japan Prospective Studies Collaboration for Aging and Dementia (JPSC-AD), identifying three novel loci significantly associated with WMH volume (P < 5 × 10 ). A subsequent trans-ethnic meta-analys

  • Multivariate genome-wide association study on tissue-sensitive diffusion metrics highlights pathways that shape the human brain - Unknown journal (n.d.) · Unknown authors · PubMed 35505052

    ABSTRACT: The molecular determinants of tissue composition of the human brain remain largely unknown. Recent genome-wide association studies (GWAS) on this topic have had limited success due to methodological constraints. Here, we apply advanced whole-brain analyses on multi-shell diffusion imaging data and multivariate GWAS to two large scale imaging genetic datasets (UK Biobank and the Adolescent Brain Cognitive Development study) to identify and validate genetic association signals. We discover 503 unique genetic loci that have impact on multiple regions of human brain. Among them, more than 79% are validated in either of two large-scale independent imaging datasets. Key molecular pathways involved in axonal growth, astrocyte-mediated neuroinflammation, and synaptogenesis during develop

  • GWAS on retinal vasculometry phenotypes - Unknown journal (n.d.) · Unknown authors · PubMed 36757925

    ABSTRACT: The eye is the window through which light is transmitted and visual sensory signalling originates. It is also a window through which elements of the cardiovascular and nervous systems can be directly inspected, using ophthalmoscopy or retinal imaging. Measurements of ocular parameters may therefore offer important information on the physiology and homeostasis of these two important systems. Here we report the results of a genetic characterisation of retinal vasculature. Four genome-wide association studies performed on different aspects of retinal vasculometry phenotypes, such as arteriolar and venular tortuosity and width, found significant similarities between retinal vascular characteristics and cardiometabolic health. Our analyses identified 119 different regions of associati

  • Understanding the genetic determinants of the brain with MOSTest - Unknown journal (n.d.) · Unknown authors · PubMed 32665545

    ABSTRACT: Regional brain morphology has a complex genetic architecture, consisting of many common polymorphisms with small individual effects. This has proven challenging for genome-wide association studies (GWAS). Due to the distributed nature of genetic signal across brain regions, multivariate analysis of regional measures may enhance discovery of genetic variants. Current multivariate approaches to GWAS are ill-suited for complex, large-scale data of this kind. Here, we introduce the Multivariate Omnibus Statistical Test (MOSTest), with an efficient computational design enabling rapid and reliable inference, and apply it to 171 regional brain morphology measures from 26,502 UK Biobank participants. At the conventional genome-wide significance threshold of α = 5 × 10−8, MOS
