Genes affected

BCLAF1 (HGNC:16863): (BCL2 associated transcription factor 1) This gene encodes a transcriptional repressor that interacts with several members of the BCL2 family of proteins. Overexpression of this protein induces apoptosis, which can be suppressed by co-expression of BCL2 proteins. The protein localizes to dot-like structures throughout the nucleus, and redistributes to a zone near the nuclear envelope in cells undergoing apoptosis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.2272C>T (p.P758S) alteration is located in exon 10 (coding exon 8) of the BCLAF1 gene. This alteration results from a C to T substitution at nucleotide position 2272, causing the proline (P) at amino acid position 758 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
