DNA (cytosine-5)-methyltransferase 3A

The DNMT3A gene encodes a methyltransferase that is responsible for methylation of CpG islet in genomic DNA. So this emzyme plays an important role in gene silicing during development and epigenetic modification. Mutations cause autosomal dominant Tatton-Brown-Rahman syndrome.
