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

May 18, 2023

The c.1150T>C (p.Y384H) alteration is located in exon 8 (coding exon 7) of the SERPINB3 gene. This alteration results from a T to C substitution at nucleotide position 1150, causing the tyrosine (Y) at amino acid position 384 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
