    Summary
    This gene encodes a nuclear polyglutamine-binding protein that is involved with transcription activation. The encoded protein contains a WW domain. Mutations in this gene have been found in patients with Renpenning syndrome 1 and other syndromes with X-linked mental retardation. Multiple alternatively spliced transcript variants that encode different protein isoforms have been described for this gene.[provided by RefSeq, Nov 2009]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

    Suppressed Reference Sequence(s)

    The following Reference Sequences have been suppressed. Explain

    1. NM_001032385.1: Suppressed sequence

      Description
      NM_001032385.1: This RefSeq was permanently suppressed because it is a nonsense-mediated mRNA decay (NMD) candidate.
    2. NM_144494.1: Suppressed sequence

      Description
      NM_144494.1: This RefSeq was permanently suppressed because it contains intronic sequence and insufficient support exists for the transcript and the protein.
