Summary
This gene encodes a protein that is expressed at high levels in cardiac and skeletal muscle. Mutations in this gene have been associated with a number of clinical disorders including Barth syndrome, dilated cardiomyopathy (DCM), hypertrophic DCM, endocardial fibroelastosis, and left ventricular noncompaction (LVNC). Multiple transcript variants encoding different isoforms have been described. A long form and a short form of each of these isoforms is produced; the short form lacks a hydrophobic leader sequence and may exist as a cytoplasmic protein rather than being membrane-bound. Other alternatively spliced transcripts have been described but the full-length nature of all these transcripts is not known. [provided by RefSeq, Jul 2008]
Annotation information
Note: TAZ (GeneID 6901) and WWTR1 (GeneID 25937) loci share the TAZ symbol/alias in common. TAZ is a widely used alternative name for the transcriptional coactivator with PDZ-binding motif (WWTR1) conflicting with the official symbol for tafazzin (TAZ). [19 Jun 2012]

NCBI Reference Sequences (RefSeq)

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.

RNA

  1. NR_024048.3 RNA Sequence

    Status: REVIEWED

    Description
    Transcript Variant: This variant (6) uses an alternate donor splice site at one of the coding exons, and is also lacking an internal coding exon compared to variant 1. This results in premature translation termination rendering this transcript susceptible to NMD. This variant has transcript support, but is not expected to encode a viable protein product.
