    Summary
    This gene encodes a member of the apolipoprotein L family. The encoded protein may play a role in lipid exchange and transport throughout the body, as well as in reverse cholesterol transport from peripheral cells to the liver. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2020]

    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: REVIEWED

      Description
      Transcript Variant: This variant (b) lacks an internal exon in the 5' region, which results in upstream AUG start codon, compared to variant a. The resulting isoform (2) has a longer and distinct N-terminus, compared to isoform 1. Isoform 2 is thought to be a secreted protein.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (c) has multiple differences in the coding region compared to variant a, one of which results in a frameshift. The resulting isoform is shorter than isoform 1 and similar to it only at the N-terminus.
