Proteomic profiling identified 100 statistically significant proteins, with a critical subset of shared proteins including Peroxisomal biogenesis factor 14, Glutaredoxin-2, Creatine kinase mitochondrial 2, and Selenocysteine insertion sequence-binding protein identified between the MMVD C WAZ and CKD Stage 2 groups. The gene discussed is PEX14; the disease is chronic kidney disease.
