Ambry Genetics

Sep 29, 2022

The c.668C>A (p.S223Y) alteration is located in exon 2 (coding exon 2) of the TAAR2 gene. This alteration results from a C to A substitution at nucleotide position 668, causing the serine (S) at amino acid position 223 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
