The heatmap in Fig. 8c shows that Ftl1, Gstm1, Glyat, Sdha, Ces1d, Idh2, Nipsnap1 and Ces1g are all induced by DEN, Hjv deficiency or iron; moreover, they tend to be “corrected” by iron depletion in Hjv−/− mice (except Ces1d). The gene discussed is GLYAT; the disease is hyperinsulinemic hypoglycemia, familial, 4.
