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.398G>T (p.R133L) alteration is located in exon 2 (coding exon 1) of the TIPARP gene. This alteration results from a G to T substitution at nucleotide position 398, causing the arginine (R) at amino acid position 133 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
