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]

SERPINB5 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=1.11190755E-4).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.551 is higher than 0.05.
