Genes affected

TIPARP (HGNC:23696): (TCDD inducible poly(ADP-ribose) polymerase) This gene encodes a member of the poly(ADP-ribose) polymerase superfamily. Studies of the mouse ortholog have shown that the encoded protein catalyzes histone poly(ADP-ribosyl)ation and may be involved in T-cell function. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2010]

The c.673G>C (p.E225Q) alteration is located in exon 2 (coding exon 1) of the TIPARP gene. This alteration results from a G to C substitution at nucleotide position 673, causing the glutamic acid (E) at amino acid position 225 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
