The c.1167G>C (p.L389F) alteration is located in exon 14 (coding exon 13) of the OC90 gene. This alteration results from a G to C substitution at nucleotide position 1167, causing the leucine (L) at amino acid position 389 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
