The c.942A>G (p.I314M) alteration is located in exon 2 (coding exon 2) of the TAAR2 gene. This alteration results from a A to G substitution at nucleotide position 942, causing the isoleucine (I) at amino acid position 314 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
