When removing count-based terms, we visualized 11 signals from four Huntington’s disease modifier genes (MSH3 n = 8, LIG1 n = 1, MLH1 n = 1, RRM2B n = 1; Fig. 2B), some of which are related to neurological processes that could be relevant to Huntington’s disease. Here, LIG1 is linked to Huntington disease.
