Genes affected

HTR3D (HGNC:24004): (5-hydroxytryptamine receptor 3D) The protein encoded this gene belongs to the ligand-gated ion channel receptor superfamily. This gene encodes subunit D of the type 3 receptor for 5-hydroxytryptamine (serotonin), a biogenic hormone that functions as a neurotransmitter, a mitogen and a hormone. This hormone has been linked to neuropsychiatric disorders, including anxiety, depression, and migraine. Serotonin receptors causes fast and depolarizing responses in neurons following activation. The genes encoding subunits C, D and E of this type 3 receptor form a cluster on chromosome 3. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

The c.11A>G (p.H4R) alteration is located in exon 1 (coding exon 1) of the HTR3D gene. This alteration results from a A to G substitution at nucleotide position 11, causing the histidine (H) at amino acid position 4 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
