Genes affected

TIGD7 (HGNC:18331): (tigger transposable element derived 7) The protein encoded by this gene belongs to the tigger subfamily of the pogo superfamily of DNA-mediated transposons in humans. These proteins are related to DNA transposons found in fungi and nematodes, and more distantly to the Tc1 and mariner transposases. They are also very similar to the major mammalian centromere protein B. The exact function of this gene is not known. [provided by RefSeq, Jul 2008]

ZNF263 (HGNC:13056): (zinc finger protein 263) Enables DNA-binding transcription repressor activity, RNA polymerase II-specific and transcription cis-regulatory region binding activity. Involved in negative regulation of transcription by RNA polymerase II and positive regulation of transcription by RNA polymerase II. Located in nucleus.
