The patient was a carrier of the following heterozygous missense variants of unknown significance (VUS): (1) collagen type VI alpha 1 chain (COL6A1) gene (c.956A>G), (2) sarcoglycan alpha (SGCA) gene (c.155T>G), and 3) spectrin repeat containing nuclear envelope protein 1 (SYNE1) gene (c.17342G>A), all biomarkers of DCM [27,28,29]. Here, SYNE1 is linked to familial dilated cardiomyopathy.
