Summary
The function of this gene is not known. This gene is located in a region commonly deleted in esophageal squamous cell carcinomas. Gene expression is reduced or absent in these carcinomas and thus this is a candidate tumor suppressor gene for esophageal squamous cell carcinomas. [provided by RefSeq, Jul 2008]
Annotation information
Note: DEC1 (Gene ID: 50514) and BHLHE40 (Gene ID: 8553) share the DEC1 symbol/alias in common. DEC1 (differentially expressed in chondrocytes 1) is a widely used alternative name for basic helix-loop-helix family member e40 (BHLHE40), which can be confused with the official symbol for deleted in esophageal cancer 1 (DEC1).

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.
