The laboratory investigations (for example, elevated erythrocyte sedimentation rate and C-reactive protein level, hyponatremia, hypoalbuminemia) and echocardiographic findings might support the diagnosis [7]. About 15–25% of untreated patients might develop coronary artery aneurysms or ectasia and also end up in myocardial infarction, sudden death, or ischemic heart disease[4]. The gene discussed is CRP; the disease is Hyponatremia.
