Abstract Background and Method: The genetic cause of infantile-onset cardiomyopathy is rarely investigated. Here, we conducted whole exome sequencing (WES) and mitochondrial DNA (mtDNA) sequencing in eight patients with infantile-onset cardiomyopathy to identify genetic variations. Result: Among these patients, two (25%) had dilated cardiomyopathy (DCMP), two (25%) had left ventricular non-compaction (LVNC), and four (50%) had hypertrophic cardiomyopathy (HCMP). Except four patients identified prenatally, the remaining patients presented at a median age of 85.5 days. WES identified genetic variants in a total of seven (87.5%) patients and mtDNA sequencing in the other case. TPM1 and MYH7 variants were identified… More >
