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 cognitive disability. Multiple alternatively spliced transcript variants that encode different protein isoforms have been described for this gene.[provided by RefSeq, Nov 2009]
Expression: Ubiquitous expression in ovary (RPKM 25.3), adrenal (RPKM 17.1) and 25 other tissues See more

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.

The following Reference Sequences have been suppressed. Explain

NM_001032385.1: Suppressed sequence

Description

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