Genes affected

BCORL1 (HGNC:25657): (BCL6 corepressor like 1) The protein encoded by this gene is a transcriptional corepressor that is found tethered to promoter regions by DNA-binding proteins. The encoded protein can interact with several different class II histone deacetylases to repress transcription. Two transcript variants encoding different isoforms have been found for this gene.

The c.197G>A (p.G66E) alteration is located in exon 3 (coding exon 3) of the BCORL1 gene. This alteration results from a G to A substitution at nucleotide position 197, causing the glycine (G) at amino acid position 66 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
