Genes affected

TDP2 (HGNC:17768): (tyrosyl-DNA phosphodiesterase 2) This gene encodes a member of a superfamily of divalent cation-dependent phosphodiesterases. The encoded protein associates with CD40, tumor necrosis factor (TNF) receptor-75 and TNF receptor associated factors (TRAFs), and inhibits nuclear factor-kappa-B activation. This protein has sequence and structural similarities with APE1 endonuclease, which is involved in both DNA repair and the activation of transcription factors. [provided by RefSeq, Jul 2008]

The c.731T>A (p.V244D) alteration is located in exon 6 (coding exon 6) of the TDP2 gene. This alteration results from a T to A substitution at nucleotide position 731, causing the valine (V) at amino acid position 244 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
