Genes affected

TSNAX (HGNC:12380): (translin associated factor X) This gene encodes a protein which specifically interacts with translin, a DNA-binding protein that binds consensus sequences at breakpoint junctions of chromosomal translocations. The encoded protein contains bipartite nuclear targeting sequences that may provide nuclear transport for translin, which lacks any nuclear targeting motifs. [provided by RefSeq, Jul 2008]

TSNAX links:

TSNAX-DISC1 (HGNC:49177): (TSNAX-DISC1 readthrough (NMD candidate)) This gene represents naturally occurring read-through transcription between the neighboring TSNAX (translin-associated factor X) and DISC1 (disrupted in schizophrenia 1) genes on chromosome 1. Alternative splicing results in multiple transcript variants, all of which are candidates for nonsense-mediated mRNA decay (NMD) and are unlikely to be protein-coding. These alterations in gene processing may be associated with risk for psychiatric illness, most notably, schizophrenia. [provided by RefSeq, Nov 2010]
