The variant allele was found at a frequency of 0.111 in 152,186 control chromosomes in the GnomAD database, including 1,280 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.11 (1280 hom., cov: 32)
• Consequence: SULF2 NM_001387048.1 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.639

Genes affected

SULF2 (HGNC:20392): (sulfatase 2) Heparan sulfate proteoglycans (HSPGs) act as coreceptors for numerous heparin-binding growth factors and cytokines and are involved in cell signaling. Heparan sulfate 6-O-endosulfatases, such as SULF2, selectively remove 6-O-sulfate groups from heparan sulfate. This activity modulates the effects of heparan sulfate by altering binding sites for signaling molecules (Dai et al., 2005 [PubMed 16192265]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.93).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.155 is higher than 0.05.
