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.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (3) lacks several exons, and its 3' terminal exon extends past a splice site that is used in variant 1. This results in a novel 3' coding region and 3' UTR, compared to variant 1. The encoded isoform (2) has a shorter and distinct C-terminus, compared to isoform 1.

    Description
    Transcript Variant: This variant (4) lacks several exons, and uses an alternate 3'-terminal exon, compared to variant a. This results in a novel 3' coding region and 3' UTR, compared to variant 1. The encoded isoform (3) has a shorter and distinct C-terminus, compared to isoform 1.
