Genes affected

SERPINB5 (HGNC:8949): (serpin family B member 5) Predicted to enable serine-type endopeptidase inhibitor activity. Predicted to be involved in negative regulation of endopeptidase activity. Predicted to act upstream of or within several processes, including extracellular matrix organization; prostate gland morphogenesis; and regulation of epithelial cell proliferation. Located in cytoplasm. Biomarker of hepatocellular carcinoma. [provided by Alliance of Genome Resources, Apr 2022]

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=0.04249561).
