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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 09, 2023The c.1103C>T (p.P368L) alteration is located in exon 8 (coding exon 7) of the SERPINB3 gene. This alteration results from a C to T substitution at nucleotide position 1103, causing the proline (P) at amino acid position 368 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
