The c.2046C>G (p.F682L) alteration is located in exon 12 (coding exon 12) of the QSOX2 gene. This alteration results from a C to G substitution at nucleotide position 2046, causing the phenylalanine (F) at amino acid position 682 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
