Possible link of SOD2 to kallikrein-kinin system

Trans-association with Superoxide dismutase [Mn], mitochondrial (SOD2). Replication in QMDiab not attempted due to lack of a tagging SNP. Genetic variant in cis impacts factor XII levels (not in SOMAscan panel). Verweij et al. [PubMed] report a "Genome-wide association study on plasma levels of midregional-proadrenomedullin and C-terminal-pro-endothelin-1" and state "The minor variants in KLKB1 (rs4253238) and F12 (rs2731672), both part of the kallikrein-kinin system, were associated with higher MR-pro-ADM (P=4.46E-52 and P=5.90E-24, respectively) and higher CT-pro-ET-1 levels (P=1.23E-122 and P=1.26E-67, respectively). Epistasis analyses showed a significant interaction between the sentinel SNP of F12 and KLKB1 for both traits." Link to SOD2 not clear. Confirms strong GWAS hits. Endothelin-1 (ET-1) and adrenomedullin (ADM) are circulating vasoactive peptides and predictors of cardiac death and heart failure.
