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]

Collection Method:clinical testing

The c.1100C>T (p.S367L) 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 1100, causing the serine (S) at amino acid position 367 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
