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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2022The c.371C>T (p.A124V) alteration is located in exon 2 (coding exon 1) of the TIPARP gene. This alteration results from a C to T substitution at nucleotide position 371, causing the alanine (A) at amino acid position 124 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
