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=0.2004705).

Collection Method: clinical testing

The c.1067C>T (p.P356L) alteration is located in exon 7 (coding exon 7) of the TOX gene. This alteration results from a C to T substitution at nucleotide position 1067, causing the proline (P) at amino acid position 356 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
