The c.386C>T (p.P129L) 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 386, causing the proline (P) at amino acid position 129 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
