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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), TRRAP. . Gene score misZ 8.173 (greater than the threshold 3.09). Trascript score misZ 10.503 (greater than threshold 3.09). GenCC has associacion of gene with autosomal dominant nonsyndromic hearing loss, developmental delay with or without dysmorphic facies and autism, hearing loss, autosomal dominant 75, complex neurodevelopmental disorder with or without congenital anomalies.

BP4

Computational evidence support a benign effect (MetaRNN=0.40822083).
