nominally significantP = 3.8 × 10 −2
The associations with non-synonymous and the NSD20 variants in the dichotomous group remained nominally significant ( P = 3.8 × 10 −2 and P = 4.4 × 10 −2 , respectively) even after the removal of the R377W and R507H variants previously identified in GeM-HD GWAS (Supplementary Table 3a ).
