Genes affected

CREBBP (HGNC:2348): (CREB binding protein) This gene is ubiquitously expressed and is involved in the transcriptional coactivation of many different transcription factors. First isolated as a nuclear protein that binds to cAMP-response element binding protein (CREB), this gene is now known to play critical roles in embryonic development, growth control, and homeostasis by coupling chromatin remodeling to transcription factor recognition. The protein encoded by this gene has intrinsic histone acetyltransferase activity and also acts as a scaffold to stabilize additional protein interactions with the transcription complex. This protein acetylates both histone and non-histone proteins. This protein shares regions of very high sequence similarity with protein p300 in its bromodomain, cysteine-histidine-rich regions, and histone acetyltransferase domain. Mutations in this gene cause Rubinstein-Taybi syndrome (RTS). Chromosomal translocations involving this gene have been associated with acute myeloid leukemia. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Feb 2009]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -19 ACMG points.

PP2

Missense variant in the CREBBP gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 106 curated pathogenic missense variants (we use a threshold of 10). The gene has 165 curated benign missense variants. Gene score misZ: 3.8991 (above the threshold of 3.09). Trascript score misZ: 4.7573 (above the threshold of 3.09). GenCC associations: The gene is linked to Menke-Hennekam syndrome 1, Rubinstein-Taybi syndrome due to CREBBP mutations, Rubinstein-Taybi syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.005286813).

BP6

Variant 16-3778056-C-A is Benign according to our data. Variant chr16-3778056-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 133945.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
