RCV001355125 | SCV001549914 | likely benign | not provided | no assertion criteria provided | clinical testing | The EP300 p.Ser106Gly variant was not identified in the literature nor was it identified in Cosmic or LOVD 3.0. The variant was identified in dbSNP (ID: rs150245975) and ClinVar (classified as likely benign by Illumina for Rubinstein-Taybi Syndrome). The variant was identified in control databases in 136 of 282856 chromosomes at a frequency of 0.000481 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: European (non-Finnish) in 129 of 129168 chromosomes (freq: 0.000999), African in 5 of 24964 chromosomes (freq: 0.0002), Other in 1 of 7224 chromosomes (freq: 0.000138) and Latino in 1 of 35440 chromosomes (freq: 0.000028), but was not observed in the Ashkenazi Jewish, East Asian, European (Finnish) or South Asian populations. The p.Ser106 residue is conserved in mammals but not in more distantly related organisms however computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and three of four in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) 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. |
