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]

The EP300 c.1150T>G variant is predicted to result in the amino acid substitution p.Ser384Ala. To our knowledge, this variant has not been reported in the literature in association with EP300-related disease. Of note, this variant was reported in healthy individuals per a genome sequencing study (Supplementary Table S1, Bodian et al. 2014. PubMed ID: 24728327). This variant is reported in 0.0094% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant has conflicting interpretations of benign and uncertain in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/134063/). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
