The c.821C>T (p.A274V) alteration is located in exon 1 (coding exon 1) of the OR8J3 gene. This alteration results from a C to T substitution at nucleotide position 821, causing the alanine (A) at amino acid position 274 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
