A study by Ayoglu et al. [41] used an affinity proteomics approach and identified 11 serum protein biomarkers associated with DMD, of which 5 were novel and included myosin light chain-3 (MYL3), troponin T, fast skeletal muscle (TNNT3), plastin-2 (LCP1), protein phosphatase 1F (PPM1F) and electron transfer flavoprotein A (ETFA). The gene discussed is MYL3; the disease is Duchenne muscular dystrophy.
