Genes affected

ZDBF2 (HGNC:29313): (zinc finger DBF-type containing 2) This gene encodes a protein containing DBF4-type zinc finger domains. This gene is imprinted and paternally expressed in lymphocytes but is more stochastically expressed in the placenta. Alternative splicing results in multiple transcript variants.
