We postulate that the novel MVI-AKAP9 interaction could also be important in cardiac muscle since, on one hand, AKAP9 was shown to play a crucial role in the proper functioning of the heart [18] and, on the other hand, mutated MVI was shown to be associated with hypertrophic cardiomyopathy [12]. The gene discussed is AKAP9; the disease is hypertrophic cardiomyopathy.
