5-HT2A-rs6314

myDNA Comprehensive Health Report, NutriPATH

Reference range:   Wild Type , Heterozygous, Homozygous

The 5-HT2A-rs6314 marker is a single nucleotide polymorphism (SNP) in the HTR2A gene, which encodes the 5-HT2A serotonin receptor. This receptor plays a key role in regulating mood, cognition, sleep, appetite, and how the brain responds to serotonin — one of the most important neurotransmitters for mental health and emotional balance.

The rs6314 SNP involves a C to T substitution at a specific point in the gene, leading to a change in the receptor’s structure and function. Because serotonin receptors influence both the central nervous system and peripheral systems (including gut function and cardiovascular health), variations in this gene may affect both mental and physical health outcomes.

5-Hydroxyindolacetic acid (5-HIAA)

Urine

Chemistry Tests, Abdali Hospital

Optimal range:   0 - 15 mg/24 hr

5-Hydroxyindolacetic acid (5-HIAA) is an important chemical compound in the medical and biochemical fields, acting as a primary interest for its role as a metabolite in the human body. Essentially, it's what remains after serotonin, a key neurotransmitter responsible for regulating mood, appetite, and sleep among other functions, is broken down. The body converts serotonin into 5-HIAA, which is then excreted in the urine.

Organic Acids Profile (US BioTek), US BioTek

Optimal range:   1.17 - 8.06 ug/mg creatinine

5-Hydroxyindoleacetic acid (5HIAA) is a breakdown product of serotonin that is excreted in the urine. Serotonin is a hormone found at high levels in many body tissues. Serotonin and 5HIAA are produced in excess amounts by carcinoid tumors, and levels of these substances may be measured in the urine to test for carcinoid tumors.
