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]

TIPARP-AS1 (HGNC:41028): (TIPARP antisense RNA 1)

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• BS2: High AC in GnomAd4 at 8 AD gene.
