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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 28, 2024The c.1721C>T (p.T574I) alteration is located in exon 6 (coding exon 4) of the BCLAF1 gene. This alteration results from a C to T substitution at nucleotide position 1721, causing the threonine (T) at amino acid position 574 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
