The variant received 2 classification points (ACGS-UK Somatic Oncogenicity v2025). O3_Moderate

The NM_004385.5(VCAN):c.6721_6723delAGAinsTCG (p.Arg2241Ser) variant causes a missense change. The gene VCAN is a tumor suppressor gene (CancerMine: 1 TSG, 3 oncogene, 2 driver citations). The gene VCAN is a known oncogene (CancerMine: 1 TSG, 3 oncogene, 2 driver citations). The gene VCAN is a cancer driver gene (CancerMine: 1 TSG, 3 oncogene, 2 driver citations). Note: allele frequency estimates from gnomAD may be inaccurate for this variant type (MNP or indel longer than 3 bp) due to technology limitations. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.R2241= (synonymous): Benign (ClinVar VariationId 198797, 2 stars)

Genes affected

VCAN (HGNC:2464): (versican) This gene is a member of the aggrecan/versican proteoglycan family. The protein encoded is a large chondroitin sulfate proteoglycan and is a major component of the extracellular matrix. This protein is involved in cell adhesion, proliferation, proliferation, migration and angiogenesis and plays a central role in tissue morphogenesis and maintenance. Mutations in this gene are the cause of Wagner syndrome type 1. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2009]
