Genes affected

SERPINB3 (HGNC:10569): (serpin family B member 3) Enables cysteine-type endopeptidase inhibitor activity; protease binding activity; and virus receptor activity. Involved in several processes, including autocrine signaling; paracrine signaling; and regulation of cellular protein metabolic process. Located in cytoplasmic vesicle; extracellular exosome; and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

SERPINB3 links:

SERPINB11 (HGNC:14221): (serpin family B member 11) Predicted to enable serine-type endopeptidase inhibitor activity. Predicted to be involved in negative regulation of endopeptidase activity. Predicted to be located in cytoplasm. Predicted to be active in extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Jun 21, 2023

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
