Also known as
This locus appears to be a transcribed pseudogene of the BMS1 homolog of yeast ribosome assembly protein on chromosome 10 that has arisen from duplication of the 3' half of the parent gene. Frameshifts and premature stop codons are present in this pseudogene compared to the parent gene. This gene lies in the immunoglobulin lambda gene cluster on chromosome 22q11.21.[provided by RefSeq, Mar 2009]

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.
