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]

The c.856G>C (p.A286P) alteration is located in exon 7 (coding exon 6) of the SERPINB5 gene. This alteration results from a G to C substitution at nucleotide position 856, causing the alanine (A) at amino acid position 286 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
