    Summary
    This gene encodes a member of the serpin family of proteins, a group of proteins that inhibit serine proteases. The encoded intracellular glycoprotein is localized at the endoplasmic reticulum. This gene is a polymorphic pseudogene, with the non-functional allele being predominant in some populations. Some individuals, as represented by the reference genome allele, contain a 2kb coding region deletion and a start code mutation. [provided by RefSeq, Feb 2014]
    Annotation information
    Note: Genetic polymorphisms result in both protein coding and non-coding alleles of this gene.
    Note: Population studies indicate that this gene is polymorphic. Deletions, frameshift mutations and a critical start codon mutation (ATG->ATA) have been found in some populations as well as an allele that can encode a functional protein. This gene may be an evolving pseudogene (PMID: 17135331). The reference genome contains the start codon mutation and has a coding region deletion. The NCBI RefSeq Project therefore treats this as a pseudogene. [13 Feb 2013]

    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.
