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]

Ambry Genetics

Jan 03, 2024

The c.896T>C (p.I299T) alteration is located in exon 2 (coding exon 2) of the HTR5A gene. This alteration results from a T to C substitution at nucleotide position 896, causing the isoleucine (I) at amino acid position 299 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
