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]

This sequence change falls in intron 1 of the TRIP13 gene. It does not directly change the encoded amino acid sequence of the TRIP13 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs762118615, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with TRIP13-related conditions. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
