Summary
This biological region is found upstream of the adenosine deaminase (ADA) gene and is known to undergo Alu-repeat-mediated non-allelic homologous recombination (NAHR) with the proximal ADA Alu-mediated recombination region, located about 3 kb centromere-distal of this region on the reference genome. Recombination between these regions can result in a deletion of the intervening sequence, including an exon and the promoter region of the ADA gene. The deletion of about 3.2 kb that results from NAHR between Alu elements results in adenosine deaminase (ADA)-deficient severe combined immunodeficiency (SCID), a syndrome characterized by a deficiency in B and T cell function.

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.
