In the study of pathology, the exploration of Andersen Disease is one which has not been fully attempted. Andersen Disease is an extremely rare disorder which is believed to be passed via hereditary mutations in the KCNJ2 gene. This paper is designed to promote a better understanding of Andersen Disease based upon the available literature. It is necessary to note that due to the rare nature of the disease, there have not been too many studies done specifically on charting the diagnosis and the life cycle of Andersen Disease in a wide sample population.
