Loss of Rearranged L-Myc Fusion (RLF) results in defects in heart development in the mouse.

This study provides the first evidence that RLF is required for normal heart development in the mouse. The heart morphological defects present at high penetrance in Rlf mutants are consistent with features of LVNC in humans, and molecular analysis identified attenuated JAGGED 1 expression and NOTCH signalling as likely contributors to these defects. Our study highlights the importance of RLF-dependent epigenetic modifications to DNA for maintaining correct gene regulatory network and intercellular signalling interactions during heart chamber and septal development. Further investigations are needed to define the biochemical role of RLF in the developing heart, and whether RLF mutations are a cause of heart defects in humans.
