As shown in Table 3, the expression of certain genes such as CCL5, FCER2, GZMH, IDO1, IL10, IL13, IL1B, IL2RA, LGALS9, PDCD1LG2, PRF1, STAT1, TGFB2, and TNFSF10 was increased in IND-Pre and also in CCC-Pre patients with respect to HD (with the exception of the LGALS9 gene). Here, PDCD1LG2 is linked to Huntington disease.
