Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_014729.3(TOX):​c.1027G>T​(p.Val343Leu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V343M) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: TOX NM_014729.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 5.48
• Publications: 0 publications found

Genes affected

TOX (HGNC:18988): (thymocyte selection associated high mobility group box) The protein encoded by this gene contains a HMG box DNA binding domain. HMG boxes are found in many eukaryotic proteins involved in chromatin assembly, transcription and replication. This protein may function to regulate T-cell development.[provided by RefSeq, Apr 2009]

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.14597085).
