Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the F12 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: Factor XII is a serum glycoprotein that participates in the initiation of blood coagulation, fibrinolysis, and the generation of bradykinin and angiotensin. Prekallikrein is cleaved by factor XII to form kallikrein, which then cleaves factor XII first to alpha-factor XIIa and then trypsin cleaves it to beta- factor XIIa. Alpha-factor XIIa activates factor XI to factor XIa. {ECO:0000269|PubMed:21304106}.
• Disease: DISEASE: Factor XII deficiency (FA12D) [MIM:234000]: An asymptomatic anomaly of in vitro blood coagulation. Its diagnosis is based on finding a low plasma activity of the factor in coagulating assays. It is usually only accidentally discovered through pre-operative blood tests. Factor XII deficiency is divided into two categories, a cross-reacting material (CRM)- negative group (negative F12 antigen detection) and a CRM-positive group (positive F12 antigen detection). {ECO:0000269|PubMed:10361128, ECO:0000269|PubMed:11776307, ECO:0000269|PubMed:15205584, ECO:0000269|PubMed:15617741, ECO:0000269|PubMed:2510163, ECO:0000269|PubMed:2882793, ECO:0000269|PubMed:8049433, ECO:0000269|PubMed:8528215, ECO:0000269|PubMed:9354665}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Hereditary angioedema 3 (HAE3) [MIM:610618]: An hereditary angioedema occurring only in women. Hereditary angioedema is 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 type 3 differs from types 1 and 2 in that both concentration and function of C1 esterase inhibitor are normal. Hereditary angioedema type 3 is precipitated or worsened by high estrogen levels (e.g., during pregnancy or treatment with oral contraceptives). {ECO:0000269|PubMed:16638441, ECO:0000269|PubMed:17186468}. Note=The disease is caused by mutations affecting the gene represented in this entry.
