Genes affected

HRH3 (HGNC:5184): (histamine receptor H3) Histamine is a ubiquitous messenger molecule released from mast cells, enterochromaffin-like cells, and neurons. Its various actions are mediated by histamine receptors H1, H2, H3 and H4. This gene encodes one of the histamine receptors (H3) which belongs to the family 1 of G protein-coupled receptors. It is an integral membrane protein and can regulate neurotransmitter release. This receptor can also increase voltage-dependent calcium current in smooth muscles and innervates the blood vessels and the heart in cardiovascular system. [provided by RefSeq, Jul 2008]

Ambry Genetics

Jan 20, 2023

The c.922G>A (p.G308S) alteration is located in exon 3 (coding exon 3) of the HRH3 gene. This alteration results from a G to A substitution at nucleotide position 922, causing the glycine (G) at amino acid position 308 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
