Genes affected

SPOCK2 (HGNC:13564): (SPARC (osteonectin), cwcv and kazal like domains proteoglycan 2) This gene encodes a protein which binds with glycosaminoglycans to form part of the extracellular matrix. The protein contains thyroglobulin type-1, follistatin-like, and calcium-binding domains, and has glycosaminoglycan attachment sites in the acidic C-terminal region. Three alternatively spliced transcript variants that encode different protein isoforms have been described for this gene. [provided by RefSeq, Oct 2011]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.48).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.536 is higher than 0.05.
