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]

The c.1185C>A (p.N395K) alteration is located in exon 7 (coding exon 7) of the TOX3 gene. This alteration results from a C to A substitution at nucleotide position 1185, causing the asparagine (N) at amino acid position 395 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
