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.6950G>A variant is predicted to result in the amino acid substitution p.Arg2317Gln. To our knowledge, this variant has not been reported in the literature in a patient an EP300 related disorder. This variant is reported in 0.032% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/22-41574665-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
