| HGNC Family | Ion channels, 5-hydroxytryptamine (serotonin) receptors (HTR) |
| Name | 5-hydroxytryptamine (serotonin) receptor 3C, ionotropic |
| Description | The product of this gene belongs to the ligand-gated ion channel receptor superfamily. This gene encodes subunit C of the type 3 receptor for 5-hydroxytryptamine (serotonin), a biogenic hormone that functions as a neurotransmitter, a hormone, and a mitogen. This receptor causes fast, depolarizing responses in neurons after activation. Genes encoding subunits C, D and E form a cluster on chromosome 3. [provided by RefSeq, Jul 2008] |
| Summary |
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\n The HTR3C gene encodes one of several 5‐hydroxytryptamine type 3 (5‑HT3) receptor subunits that, when co‐assembled with the 5‑HT3A subunit, contribute to the molecular diversity and functional modulation of this ligand‐gated ion channel. Studies have demonstrated that 5‑HT3C is coexpressed with 5‑HT3A in human tissues such as myenteric neurons, suggesting a role in both enteric and central neurotransmission (1). In vitro investigations indicate that incorporation of 5‑HT3C into heteromeric receptor complexes can influence receptor assembly, surface expression, and ligand efficacy, a property further regulated by accessory factors like RIC‑3 (3,8). Clinically, non‐synonymous polymorphisms in HTR3C—such as the p.N163K variant—have been associated with altered symptom profiles; for instance, this variant has been linked to increased risk of chemotherapy‑induced vomiting (2) and greater severity of chemotherapy‑induced symptoms (6), while it also appears to modulate symptom response in irritable bowel syndrome with diarrhea (7). In addition, genetic association studies have implicated HTR3C variants in neuropsychiatric disorders, with particular associations observed in male subjects with obsessive–compulsive disorder (4) and in autism spectrum disorders (5). Collectively, these findings underscore the contribution of HTR3C to the assembly and pharmacological properties of 5‑HT3 receptor complexes, highlighting its potential as a pharmacogenomic biomarker and therapeutic target in conditions ranging from gastrointestinal dysfunction to neurodevelopmental and psychiatric disorders.\n "}]}, {"type": "t", "text": "\n "}, {"type": "p", "children": [{"type": "t", "text": "\n Citations:."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "1", "end_ref": "8"}]}, {"type": "t", "text": ""}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Johannes Kapeller, Dorothee Möller, Felix Lasitschka, et al.
