Abstract Link: Nat Genet. 2019 Jan;51(1):96105.In brief: Gain-of-function mutations altering DNMT3A are identified as a new cause of microcephalic dwarfism. Modelling of the disease in mice show that the mutations abrogate DNMT3A binding to H3K36me2 and H3K36me3 and lead to aberrant DNA methylation of Polycomb-marked regions and therefore repression ...
