Genes affected
ZNF335 (HGNC:15807): (zinc finger protein 335) The protein encoded by this gene enhances transcriptional activation by ligand-bound nuclear hormone receptors. However, it does this not by direct interaction with the receptor, but by direct interaction with the nuclear hormone receptor transcriptional coactivator NRC. The encoded protein may function by altering local chromatin structure. [provided by RefSeq, Jul 2008]
ZNF335 Gene-Disease associations (from GenCC):
  • microcephalic primordial dwarfism due to ZNF335 deficiency
