Table 1 summarizes a search for relevant literature on the website PubMed using the terms “CaMKII,” “cardiac arrhythmia,” and “diabetes” on the 30th of May 2021. The impact of DCM on the role of CaMKII in many pathways [such as gene transcription (McKinsey, 2007)] remains to be elucidated, and could provide further treatment targets than those already described in the literature. Here, CAMK2G is linked to diabetes mellitus.
