Genes affected

HTR5A (HGNC:5300): (5-hydroxytryptamine receptor 5A) The neurotransmitter serotonin (5-hydroxytryptamine, 5-HT) has been implicated in a wide range of psychiatric conditions and also has vasoconstrictive and vasodilatory effects. The gene described in this record is a member of 5-hydroxytryptamine (serotonin) receptor family and encodes a multi-pass membrane protein that functions as a receptor for 5-hydroxytryptamine and couples to G-proteins. This protein has been shown to function in part through the regulation of intracellular Ca2+ mobilization. [provided by RefSeq, Jul 2008]

Jan 19, 2024

The c.190A>G (p.T64A) alteration is located in exon 1 (coding exon 1) of the HTR5A gene. This alteration results from a A to G substitution at nucleotide position 190, causing the threonine (T) at amino acid position 64 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
