Variant summary

Our verdict is Benign. Variant got -10 ACMG points: 0P and 10B. BP4_Moderate BA1

The NM_001080430.4(TOX3):​c.408+570A>C variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.306 in 152,182 control chromosomes in the GnomAD database, including 8,272 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.31 (8272 hom., cov: 33)
• Consequence: TOX3 NM_001080430.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.783

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]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.31).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.405 is higher than 0.05.
