Genes affected

BCOR (HGNC:20893): (BCL6 corepressor) The protein encoded by this gene was identified as an interacting corepressor of BCL6, a POZ/zinc finger transcription repressor that is required for germinal center formation and may influence apoptosis. This protein selectively interacts with the POZ domain of BCL6, but not with eight other POZ proteins. Specific class I and II histone deacetylases (HDACs) have been shown to interact with this protein, which suggests a possible link between the two classes of HDACs. Several transcript variants encoding different isoforms have been found for this gene. A pseudogene of this gene is found on chromosome Y.[provided by RefSeq, Jun 2010]

The c.5042G>A (p.R1681H) alteration is located in exon 15 (coding exon 14) of the BCOR gene. This alteration results from a G to A substitution at nucleotide position 5042, causing the arginine (R) at amino acid position 1681 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
