Genes affected

TAAR1 (HGNC:17734): (trace amine associated receptor 1) The protein encoded by this gene is a G-protein coupled receptor activated by trace amines. The encoded protein responds little or not at all to dopamine, serotonin, epinephrine, or histamine, but responds well to beta-phenylethylamine, p-tyramine, octopamine, and tryptamine. While primarily functioning in neurologic systems, there is evidence that this gene is involved in blood cell and immunologic functions as well. This gene is thought to be intronless.

The c.676G>A (p.D226N) alteration is located in exon 1 (coding exon 1) of the TAAR1 gene. This alteration results from a G to A substitution at nucleotide position 676, causing the aspartic acid (D) at amino acid position 226 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
