Ambry Genetics

Feb 23, 2023

The c.729C>G (p.I243M) alteration is located in exon 2 (coding exon 2) of the TAAR2 gene. This alteration results from a C to G substitution at nucleotide position 729, causing the isoleucine (I) at amino acid position 243 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
