Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the F9 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000000133.4. Only rare variants are included in the table.

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 IX is a vitamin K-dependent plasma protein that participates in the intrinsic pathway of blood coagulation by converting factor X to its active form in the presence of Ca(2+) ions, phospholipids, and factor VIIIa. {ECO:0000269|PubMed:1730085, ECO:0000269|PubMed:19846852, ECO:0000269|PubMed:20121197, ECO:0000269|PubMed:20121198, ECO:0000269|PubMed:2592373, ECO:0000269|PubMed:8295821}.;
Disease
DISEASE: Hemophilia B (HEMB) [MIM:306900]: An X-linked blood coagulation disorder characterized by a permanent tendency to hemorrhage, due to factor IX deficiency. It is phenotypically similar to hemophilia A, but patients present with fewer symptoms. Many patients are asymptomatic until the hemostatic system is stressed by surgery or trauma. {ECO:0000269|PubMed:10094553, ECO:0000269|PubMed:10698280, ECO:0000269|PubMed:11122099, ECO:0000269|PubMed:12588353, ECO:0000269|PubMed:12604421, ECO:0000269|PubMed:1346975, ECO:0000269|PubMed:1615485, ECO:0000269|PubMed:1902289, ECO:0000269|PubMed:1958666, ECO:0000269|PubMed:2162822, ECO:0000269|PubMed:2339358, ECO:0000269|PubMed:2372509, ECO:0000269|PubMed:2472424, ECO:0000269|PubMed:25251685, ECO:0000269|PubMed:25470321, ECO:0000269|PubMed:2592373, ECO:0000269|PubMed:2713493, ECO:0000269|PubMed:2714791, ECO:0000269|PubMed:2738071, ECO:0000269|PubMed:2753873, ECO:0000269|PubMed:2773937, ECO:0000269|PubMed:2775660, ECO:0000269|PubMed:3009023, ECO:0000269|PubMed:3243764, ECO:0000269|PubMed:3401602, ECO:0000269|PubMed:3790720, ECO:0000269|PubMed:6603618, ECO:0000269|PubMed:7981722, ECO:0000269|PubMed:8076946, ECO:0000269|PubMed:8199596, ECO:0000269|PubMed:8257988, ECO:0000269|PubMed:8295821, ECO:0000269|PubMed:8680410, ECO:0000269|PubMed:9169594, ECO:0000269|PubMed:9222764, ECO:0000269|PubMed:9452115, ECO:0000269|PubMed:9590153, ECO:0000269|PubMed:9600455}.
