Common Genetic Variation Indicates Separate Causes for Periventricular and Deep White Matter Hyperintensities

Periventricular white matter hyperintensities (WMH; PVWMH) and deep WMH (DWMH) are regional classifications of WMH and reflect proposed differences in cause. In the first study, to date, we undertook genome-wide association analyses of DWMH and PVWMH to show that these phenotypes have different genetic underpinnings.Participants were aged 45 years and older, free of stroke and dementia. We conducted genome-wide association analyses of PVWMH and...
