Why the study?
Mechanisms underlying the selective susceptibility of left ventricles to dilation and dysfunction in LVNC, and how PRDM16 deficiency causes LVNC, remain unknown.
Does cardiomyocyte-specific ablation of Prdm16 cause left ventricular noncompaction cardiomyopathy phenotypes in mice?
Population
Prdm16 cardiomyocyte-specific knockout mice
Comparison
Cardiomyocyte-specific ablation of Prdm16 vs controls
Design
Preclinical animal model and mechanistic molecular study

Should not yet change LVNC care; leaves open compact-myocardium identity as a targetable mechanism of selective LV failure.
Does cardiomyocyte-specific ablation of Prdm16 cause left ventricular noncompaction cardiomyopathy phenotypes in mice?
PRDM16 is essential for maintaining compact cardiomyocyte identity, and its deficiency leads to left ventricular noncompaction cardiomyopathy phenotypes in mice.
