Currently, creatine kinase-MB, myoglobin, cardiac forms of troponin T (cTnT), and cardiac troponin I (cTnI) are considered key biomarkers for diagnosis of MI with cTnT and cTnI as the gold standards among the three since they are highly specific to cardiac tissue injuries [4]. The gene discussed is TNNT2; the disease is myocardial infarction.
