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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 05, 2022The c.944T>G (p.M315R) alteration is located in exon 3 (coding exon 3) of the HTR6 gene. This alteration results from a T to G substitution at nucleotide position 944, causing the methionine (M) at amino acid position 315 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
