Genes affected

TRIP13 (HGNC:12307): (thyroid hormone receptor interactor 13) This gene encodes a protein that interacts with thyroid hormone receptors, also known as hormone-dependent transcription factors. The gene product interacts specifically with the ligand binding domain. This gene is one of several that may play a role in early-stage non-small cell lung cancer. [provided by RefSeq, Oct 2009]

ACMG classification

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.066974595 fraction of the gene. Cryptic splice site detected, with MaxEntScore 4.6, offset of 2, new splice context is: agggtgtttgggttccacAGtgg. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 5-907987-G-C is Pathogenic according to our data. Variant chr5-907987-G-C is described in ClinVar as Pathogenic. ClinVar VariationId is 431046.Status of the report is no_assertion_criteria_provided, 0 stars.
