WebMast cells produce histamine, a substance involved in inflammatory and allergic reactions and in the production of stomach acid. Because the number of mast cells increases, levels of histamine increase. Histamine can cause many symptoms, including digestive problems. Mastocytosis is rare. Histamine is released by mast cells as an immune response and is later degraded primarily by two enzymes: diamine oxidase (DAO), coded by AOC1 genes, and histamine-N-methyltransferase (HNMT), coded by the HNMT gene. The presence of single nucleotide polymorphisms (SNPs) at these genes are associated with a wide variety of disorders caused by an overactive immune system, from ulcerative colitis to autism spectrum disorder (ASD). Histamine degradation is crucia…
