WebPhospholamban Cardiomyopathy (PLN, or the c.40_42del gene mutation) is a genetic heart muscle disease that can cause life-threatening cardiac arrhythmias. There are 2 types of gene mutations: gene carriers can have the DCM variant (Dilated Cardiomyopathy) or the ACM one (Arrhythmogenic Cardiomyopathy). WebPhospholamban (PLN) plays a key role in calcium handling in heart muscle cells and as such impacts on proper contraction and relaxation of the heart.
