Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the SERPING1 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Activation of the C1 complex is under control of the C1- inhibitor. It forms a proteolytically inactive stoichiometric complex with the C1r or C1s proteases. May play a potentially crucial role in regulating important physiological pathways including complement activation, blood coagulation, fibrinolysis and the generation of kinins. Very efficient inhibitor of FXIIa. Inhibits chymotrypsin and kallikrein. {ECO:0000269|PubMed:8495195}.
• Disease: DISEASE: Hereditary angioedema (HAE) [MIM:106100]: An autosomal dominant disorder characterized by episodic local swelling involving subcutaneous or submucous tissue of the upper respiratory and gastrointestinal tracts, face, extremities, and genitalia. Hereditary angioedema due to C1 esterase inhibitor deficiency is comprised of two clinically indistinguishable forms. In hereditary angioedema type 1, serum levels of C1 esterase inhibitor are decreased, while in type 2, the levels are normal or elevated, but the protein is non-functional. {ECO:0000269|PubMed:12773530, ECO:0000269|PubMed:1363816, ECO:0000269|PubMed:1451784, ECO:0000269|PubMed:14635117, ECO:0000269|PubMed:16409206, ECO:0000269|PubMed:2118657, ECO:0000269|PubMed:2296585, ECO:0000269|PubMed:22994404, ECO:0000269|PubMed:2365061, ECO:0000269|PubMed:24456027, ECO:0000269|PubMed:3178731, ECO:0000269|PubMed:7814636, ECO:0000269|PubMed:7883978, ECO:0000269|PubMed:8172583, ECO:0000269|PubMed:8529136, ECO:0000269|PubMed:8755917, ECO:0000269|Ref.41}.
