In version V52, Reactome has broadened its coverage of Disease to include Hereditary fructose intolerance, Essential fructosuria, Intestinal disaccharidase deficiencies, and Diseases associated with TLR signaling cascade.
New Metabolic pathways include Fructose biosynthesis, Lactose synthesis, and Melanin biosynthesis and Post-translational protein modification has been expanded to cover SUMOylation of DNA damage response and repair proteins.
The DNA repair pathways Base excision repair, DNA damage bypass, and DNA damage reversal have been revised and within Signal transduction, RHO GTPase Effectors is new and Deactivation of the beta-catenin transactivating complex has been updated.
New pathways have also been added to the topics of Gene Expression (TP53 regulates metabolic genes), Immune system (C-type lectin receptors (CLRs), Chromatin organization (PKMTs methylate histone lysines), and Programmed cell death (Regulated necrosis).
New pathway Illustrations are available for Circadian clock, DNA replication, DNA strand elongation, Immune system, Innate immune system, Membrane trafficking, Muscle contraction, and Visual phototransduction.

Reactome comprises 8,169 human reactions involving the 8,183 protein products of 7,954 human genes, and 1,449 small molecules. These reactions are organized into 1,762 pathways, supported by 18,900 PubMed literature references. We have projected these reactions onto 98,602 orthologous proteins, creating 19,039 orthologous pathways in 18 model organisms.
