WWOX and multiple sclerosis: Evidence linking WWOX function with oligodendrocyte pathology is starting to emerge (International Multiple Sclerosis Genetics C, 2019; International Multiple Sclerosis Genetics C et al, 2013; Jakel et al, 2019; Matsushita et al, 2015; Ziliotto et al, 2019); however, less is known about the cell‐autonomous functions of WWOX in oligodendrocytes.
