Genes affected

SAP30L (HGNC:25663): (SAP30 like) Enables several functions, including non-sequence-specific DNA binding activity, bending; phosphatidylinositol phosphate binding activity; and zinc ion binding activity. Involved in negative regulation of transcription by RNA polymerase II. Located in fibrillar center and nucleoplasm. Part of histone deacetylase complex.
