We also found evidence of enrichment for pathways involved in the phosphatidylinositol signaling system and the inositol phosphate metabolism, in the mammalian target of rapamycin (mTOR) and the vascular endothelial growth factor (VEGF) signaling pathways, and in the focal adhesion and the Huntington disease pathways (Table 2, Supplementary Table 2). This evidence concerns the gene MTOR and juvenile Huntington disease.
