The c.1025C>A (p.T342N) 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 1025, causing the threonine (T) at amino acid position 342 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
