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 was made for transcript

Our verdict: Benign. The variant received -14 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.78).

BP6

Variant 16-3729218-C-T is Benign according to our data. Variant chr16-3729218-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 158389.

BP7

Synonymous conserved (PhyloP=-5.26 with no splicing effect.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00112 (168/150216) while in subpopulation SAS AF = 0.00445 (21/4716). AF 95% confidence interval is 0.00298. There are 0 homozygotes in GnomAd4. There are 82 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High AC in GnomAd4 at 168 AD gene.
