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.

Ambry Genetics

Feb 13, 2023

The c.265T>C (p.Y89H) alteration is located in exon 1 (coding exon 1) of the HTR6 gene. This alteration results from a T to C substitution at nucleotide position 265, causing the tyrosine (Y) at amino acid position 89 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
