On the other hand, the KEGG results showed that immune-related pathways such as NOD-like receptor signaling pathway, Natural killer cell mediated cytotoxicity, C-type lectin receptor signaling pathway, and Th1/2/17 cell differentiation, and some neurorelated diseases, Huntington's disease and Alzheimer's disease were also enriched in mTBI. This evidence concerns the gene CLEC4D and Huntington disease.
