Genes affected

SNAPC2 (HGNC:11135): (small nuclear RNA activating complex polypeptide 2) This gene encodes a subunit of the snRNA-activating protein complex which is associated with the TATA box-binding protein. The encoded protein is necessary for RNA polymerase II and III dependent small-nuclear RNA gene transcription. Alternative splicing results in multiple transcript variants.
