Gene‐centric approach identifies new and known loci for F VIII activity and VWF antigen levels in E uropean A mericans and A frican A mericans

AssociationN=23,603Weihong Tang et al.(2015)· American Journal of Hematology

Gene-centric association study of 18,556 European Americans and 5,047 African Americans identified novel genetic loci associated with Factor VIII coagulant activity (FVIII:C) and von Willebrand factor antigen (VWF:Ag). New associations were found at KNG1 (rs710446, Ile581Thr, p=5.10×10⁻⁷ in EAs; p=3.88×10⁻³ in AAs), VWF (rs7962217, Gly2705Arg, p=6.30×10⁻⁹ in EAs; p=2.98×10⁻² in AAs), TMLHE (rs12557310, p=8.02×10⁻¹⁰ in EAs), and MAT1A (rs2236568, p=1.69×10⁻⁶ in AAs). Variants explained 14.5% of variance in FVIII:C and 15.6% in VWF:Ag.

About KNG1

This gene uses alternative splicing to generate two different proteins- high molecular weight kininogen (HMWK) and low molecular weight kininogen (LMWK). HMWK is essential for blood coagulation and assembly of the kallikrein-kinin system. Also, bradykinin, a peptide causing numerous physiological effects, is released from HMWK. Bradykinin also functions as an antimicrobial peptide with antibacterial and antifungal activity. In contrast to HMWK, LMWK is not involved in blood coagulation. Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reduces or depletes angiotensin converting enzyme 2 (ACE2), which results in an increase in levels of des-Arg(9)-bradykinin, a bioactive metabolite of bradykinin that is associated with lung injury and inflammation. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2020]
