Genes affected

TRRAP (HGNC:12347): (transformation/transcription domain associated protein) This gene encodes a large multidomain protein of the phosphoinositide 3-kinase-related kinases (PIKK) family. The encoded protein is a common component of many histone acetyltransferase (HAT) complexes and plays a role in transcription and DNA repair by recruiting HAT complexes to chromatin. Deregulation of this gene may play a role in several types of cancer including glioblastoma multiforme. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Sep 2011]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.54).
• BP6: Variant 7-98881199-T-C is Benign according to our data. Variant chr7-98881199-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 3041424.Status of the report is no_assertion_criteria_provided, 0 stars.
• BP7: Synonymous conserved (PhyloP=1.59 with no splicing effect.
• BS2: High AC in GnomAdExome4 at 14 AD gene.
