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]

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.0016816556).
• BP6: Variant 6-136269502-A-C is Benign according to our data. Variant chr6-136269502-A-C is described in ClinVar as [Benign]. Clinvar id is 3059178.Status of the report is no_assertion_criteria_provided, 0 stars.
