Genes affected

QSOX2 (HGNC:30249): (quiescin sulfhydryl oxidase 2) QSOX2 is a member of the sulfhydryl oxidase/quiescin-6 (Q6) family (QSOX1; MIM 603120) that regulates the sensitization of neuroblastoma cells for IFN-gamma (IFNG; MIM 147570)-induced cell death (Wittke et al., 2003 [PubMed 14633699]).[supplied by OMIM, Jun 2009]

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.03238681).

The c.1757G>A (p.R586K) 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 1757, causing the arginine (R) at amino acid position 586 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
