Collection Method: clinical testing

The c.2005G>A (p.V669M) alteration is located in exon 12 (coding exon 12) of the QSOX2 gene. This alteration results from a G to A substitution at nucleotide position 2005, causing the valine (V) at amino acid position 669 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
