The c.1265C>T (p.P422L) alteration is located in exon 14 (coding exon 13) of the OC90 gene. This alteration results from a C to T substitution at nucleotide position 1265, causing the proline (P) at amino acid position 422 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
