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]

The c.556G>A (p.D186N) alteration is located in exon 6 (coding exon 6) of the TSNAX gene. This alteration results from a G to A substitution at nucleotide position 556, causing the aspartic acid (D) at amino acid position 186 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
