Genes affected

HTR6 (HGNC:5301): (5-hydroxytryptamine receptor 6) This gene encodes a protein that belongs to the seven-transmembrane G protein-coupled receptor family of proteins. The encoded protein couples with the Gs alpha subunit and stimulates adenylate cyclase to activate the cyclic AMP-dependent signaling pathway. This receptor is thought to regulate cholinergic neuronal transmission in the brain. Several antidepressants and antipsychotic drugs have a high affinity for this receptor.

The c.731G>A (p.R244H) alteration is located in exon 2 (coding exon 2) of the HTR6 gene. This alteration results from a G to A substitution at nucleotide position 731, causing the arginine (R) at amino acid position 244 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
