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.

  1. NM_001304547.2 → NP_001291476.1  multivesicular body subunit 12A isoform 2

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2) differs in the 5' UTR and lacks exons in the 5' coding region which results in the use of a downstream start codon compared to variant 1. The encoded isoform (2) has a shorter N-terminus compared to isoform 1. This variant is a read-through transcript between the upstream non-coding locus (GeneID: 105221694) and the downstream MVB12A locus (GeneID: 93343).
