    Summary
    The protein encoded by this gene is thought to be a human-specific protein. Currently available evidence suggests that orthologous regions in other organisms contain sequence differences that would not support production of a protein product. Genome-wide association studies have suggested the possibility that a SNP in the 3' UTR, rs17123507, could be associated with nicotine addiction. Expression of this gene may be elevated in some individuals with Alzheimer's disease. [provided by RefSeq, Mar 2017]

    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.
