GeneDx RCV000486188 SCV000570229 likely pathogenic not provided 2017-05-01 criteria provided, single submitter clinical testing This variant is denoted PTEN c.209+2dupT or IVS3+2dupT and consists of a duplication of one nucleotide at the +2 position of intron 3. The normal sequence, with the base that is duplicated in braces, is TCTg[t]aagt, where the capital letters are exonic and lowercase are intronic. This variant disrupts the natural splice donor consensus sequence, which is conserved across species, and multiple in silico models predict this variant to destroy the nearby natural splice donor site and cause abnormal gene splicing, leading to either an abnormal message that is subject to nonsense-mediated mRNA decay or to an abnormal protein product. This variant has not, to our knowledge, been published in the literature are pathogenic or benign. PTEN c.209+2dupT was not observed in approximately 6,400 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Based on currently available evidence, we consider this variant to be likely pathogenic.
