Brain mosaic mutations
Malformations of cortical development (MCD) are largely caused by somatic mosaic mutations. Chung, Yang et al. analyze patients with MCD, identifying disease-associated genes.

The expression of murine endogenous retrovirus-L (MERVL) is transiently upregulated at the two-cell stage in mouse embryos, coinciding with zygotic genome activation and the acquisition of totipotency; however, its role in embryogenesis remains elusive. We show that nuclear expression of MERVL is required for accurate regulation of the host transcriptome and chromatin state during preimplantation development.
