    Summary
    Deletions of the 22q11.2 have been associated with a wide range of developmental defects (notably DiGeorge syndrome, velocardiofacial syndrome, conotruncal anomaly face syndrome and isolated conotruncal cardiac defects) classified under the acronym CATCH 22. The DGCR2 gene encodes a novel putative adhesion receptor protein, which could play a role in neural crest cells migration, a process which has been proposed to be altered in DiGeorge syndrome. Alternative splicing results in multiple transcript variants.[provided by RefSeq, May 2010]

    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.

    1. NR_033674.2 RNA Sequence

      Status: REVIEWED

      Description
      Transcript Variant: This variant (5) lacks an alternate in-frame exon and uses an alternate in-frame splice site in the 5' coding region, compared to variant 1, which results in a frameshift and early stop codon. The transcript is sufficiently abundant to represent as a RefSeq record; however, the predicted protein is not represented because the product is significantly truncated and the transcript is a candidate for nonsense-mediated mRNA decay (NMD).
