The expression of CLEC4D was associated with the down-regulated pathway of alanine, aspartate, and glutamate metabolism, Arrhythmogenic right ventricular cardiomyopathy, Basal cell carcinoma, DNA replication, glycine, serine and threonine metabolism, Hypertrophic cardiomyopathy, Mannose type O-glycan biosynthesis, Proximal tubule bicarbonate reclamation, Proximal tubule bicarbonate reclamation, and Ribosome biogenesis in eukaryotes (Figure 6D). The gene discussed is CLEC4D; the disease is hypertrophic cardiomyopathy.
