Although, the method through which they work is still not completely understood. Below, we'll explore the causes and medicine-free treatments for serotonin deficiency. The DDC gene provides instructions for making the aromatic l-amino acid decarboxylase (AADC) enzyme, which is important in the brain and nervous system. [ref][ref][ref]  These are found in both v.4 and v.5 for 23andMe data. This enzyme breaks down chemicals called monoamines, including serotonin, epinephrine, and norepinephrine. © Copyright 2021 Genetic Lifehacks | Moon Consulting, LLC Bozeman, MT |, The short form of this gene has associations to lower 5-HTT activity. One of the issues that many people with anxiety have in common is that they tend to suffer from low levels of the neurotransmitter, serotonin. Serotonin is a neurotransmitter that is known to improve mood and positive feelings.

The primary symptoms of Serotonin deficiency are the same as anxiety and depression, since they tend to be related. About 90% of serotonin is made in the gut and helps to regulate motility. Genetic variants can impact the amount of tryptophan that is used for serotonin. Variable number tandem repeats are not included in 23andMe or AncestryDNA data, but there are SNPs that usually go along with the serotonin transporter repeats. The production of serotonin in the brain may be reduced by advancing age, unhappy life events and stress, lack of exercise, nutritional deficiencies, lack of exposure to sunshine, hormonal changes of menopause, genetic factors, etc. Too much serotonin can result in serotonin syndrome. Thus people who carried the long/long genotype were more likely to have a positive mood in a positive environment, but they were also more negative when bad things happened.
