Abstract Link: Nat Genet. 2019 Jan;51(1):96–105.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 ...

In Brief: The 11th edition of the ‘Nosology’ is significantly expanded, now covering 771 conditions linked to 552 genes. In a major shift from previous editions, it has adopted a dyadic naming system that defines disorders based on both their phenotypic and genetic features. It continues to be a vital tool for diagnosing and communicating about genetic skeletal disorders.Commentary: The first Nosology of genetic skeletal disorders was published...
