Genes affected

EP300 (HGNC:3373): (E1A binding protein p300) This gene encodes the adenovirus E1A-associated cellular p300 transcriptional co-activator protein. It functions as histone acetyltransferase that regulates transcription via chromatin remodeling and is important in the processes of cell proliferation and differentiation. It mediates cAMP-gene regulation by binding specifically to phosphorylated CREB protein. This gene has also been identified as a co-activator of HIF1A (hypoxia-inducible factor 1 alpha), and thus plays a role in the stimulation of hypoxia-induced genes such as VEGF. Defects in this gene are a cause of Rubinstein-Taybi syndrome and may also play a role in epithelial cancer. [provided by RefSeq, Jul 2008]

Likely benign, criteria provided, single submitter	clinical testing	CeGaT Center for Human Genetics Tuebingen	Sep 01, 2024	EP300: BP4, BS2 -
Likely benign, no assertion criteria provided	clinical testing	Department of Pathology and Laboratory Medicine, Sinai Health System	-	The EP300 p.N251S variant was not identified in the literature but was identified in dbSNP (ID: rs142009367) and ClinVar (classified as benign by Invitae). The variant was identified in control databases in 36 of 282836 chromosomes at a frequency of 0.0001273, and was observed at the highest frequency in the European (non-Finnish) population in 30 of Â¬â€ Â¬â€ 129164 chromosomes (freq: 0.0002323) (Genome Aggregation Database March 6, 2019, v2.1.1). The p.N251 residue is not conserved in mammals and computational analyses (MUT Assesor, SIFT, MutationTaster, Revel, FATHMM, MetaLR, DANN) do not suggest a high likelihood of impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (Splice AI exome) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
