Moreover, the third type of dominant mutations – various duplications found in the patients with neonatal lethal cardiomyopathy – result in the expression of a fusion gene ATAD3A-ATAD3C, where the N-terminal part corresponds to the 3 A gene, whereas the C-terminal ATPase domain comes from the 3 C pseudogene. This evidence concerns the gene ATAD3C and cardiomyopathy.
