As expected, among the genes with an upregulated expression in both genotypes were S deficiency marker genes such as SULFUR DEFICIENCY INDUCED1 (SDI1), BETA‐GLUCOSIDASE 28 (BGLU28), and GAMMA‐GLUTAMYL CYCLOTRANSFERASE2;1 (GGCT2;1) (Henriquez‐Valencia et al., 2018). Here, CDKN1A is linked to hyperinsulinemic hypoglycemia, familial, 4.
