The variant received -4 classification points (ACGS-UK Somatic Oncogenicity v2025). B1_Strong

The NM_001080430.4(TOX3):c.88-31681A>G variant causes a intron change involving the alteration of a non-conserved nucleotide. The gene TOX3 is a tumor suppressor gene (CancerMine: 2 TSG citations). The variant allele was found at a cumulative frequency of 0.608 (AC=92,509) in the gnomAD database across 152,040 control chromosomes, including 28,673 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.796. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

TOX3 (HGNC:11972): (TOX high mobility group box family member 3) The protein encoded by this gene contains an HMG-box, indicating that it may be involved in bending and unwinding of DNA and alteration of chromatin structure. The C-terminus of the encoded protein is glutamine-rich due to CAG repeats in the coding sequence. A minor allele of this gene has been implicated in an elevated risk of breast cancer. Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Apr 2009]
