Genetic Variant PROCR:p.Ser219Gly (chr20-35176751-AGT-GGG) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

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

The NM_006404.5(PROCR):c.655_657delAGTinsGGG (p.Ser219Gly) variant causes a missense change. The gene PROCR is a tumor suppressor gene (CancerMine: 1 TSG 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. This exact variant is curated in the UniProt human variants database as Uncertain Significance.

Genes affected

PROCR (HGNC:9452): (protein C receptor) The protein encoded by this gene is a receptor for activated protein C, a serine protease activated by and involved in the blood coagulation pathway. The encoded protein is an N-glycosylated type I membrane protein that enhances the activation of protein C. Mutations in this gene have been associated with venous thromboembolism and myocardial infarction, as well as with late fetal loss during pregnancy. The encoded protein may also play a role in malarial infection and has been associated with cancer. [provided by RefSeq, Jul 2013]
