PLG and amyloidosis: Review of significant enrichment of upregulated pathways in cerebellum of ASD adults (FDR-adjusted p < 0.05) revealed involvement of gene sets in peptide cross-linking, regulation of proteolysis, amyloidosis, citrullination, methylation, endopeptidase and plasminogen activity, and biosynthesis of amino acids (Table 6, S4, S8, Table 2).
