YEATS4 and Aphasia: A summary of the resulting associations is given in Figure 2C. Aside from the UL endpoint, the next two strongest associations were YEATS4 association to excessive and frequent menstruation (p = 8.1e−7; two-sided Fisher’s exact test), most likely explained by comorbidity with UL, and RUVBL1 association to dysphasia and aphasia (p = 1.7e−6).
