UMOD and acute kidney injury: Previous work has shown a negative correlation between serum uromodulin and AKI in conditions like ANCA‐associated vasculitis (Tachibana et al., 2019) and ischemia–reperfusion injury (IRI; El‐Achkar et al., 2013), and between urine uromodulin and AKI in diabetes (Chakraborty et al., 2004) and patients undergoing cardiac surgery (Zhang et al., 2022).
