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 GeneticsMar 24, 2023The c.630A>G (p.I210M) alteration is located in exon 7 (coding exon 6) of the SERPINB3 gene. This alteration results from a A to G substitution at nucleotide position 630, causing the isoleucine (I) at amino acid position 210 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
