    Summary
    This gene is an antisense transcript to the KLHL1 gene (homolog to the Drosophila KELCH gene); it does not itself appear to be protein coding. A TAC/TGC trinucleotide repeat expansion that is incorporated into this gene transcript, but not the KLHL1 transcript, causes spinocerebellar ataxia type 8. Presumably the expansion interferes with normal antisense function of this transcript. [provided by RefSeq, Oct 2008]

    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.
