| Ambry Genetics | RCV000719617 | SCV000850486 | uncertain significance | Hereditary cancer-predisposing syndrome | 2017-02-15 | criteria provided, single submitter | clinical testing | The p.E285K variant (also known as c.853G>A), located in coding exon 8 of the PTEN gene, results from a G to A substitution at nucleotide position 853. The glutamic acid at codon 285 is replaced by lysine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of p.E285K remains unclear. |
| Invitae | RCV000811408 | SCV000951674 | uncertain significance | PTEN hamartoma tumor syndrome | 2018-11-02 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamic acid with lysine at codon 285 of the PTEN protein (p.Glu285Lys). The glutamic acid residue is moderately conserved and there is a small physicochemical difference between glutamic acid and lysine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with PTEN-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
