Variant summary
Our verdict is Uncertain significance. Variant got 2 ACMG points: 3P and 1B. PM2PP2BP4
The NM_000314.8(PTEN):c.692C>T(p.Pro231Leu) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,776 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P231T) has been classified as Uncertain significance.

PTEN hamartoma tumor syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 07, 2022 | ClinVar contains an entry for this variant (Variation ID: 536552). This variant has not been reported in the literature in individuals affected with PTEN-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 231 of the PTEN protein (p.Pro231Leu). 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. 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. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 02, 2022 | The p.P231L variant (also known as c.692C>T), located in coding exon 7 of the PTEN gene, results from a C to T substitution at nucleotide position 692. The proline at codon 231 is replaced by leucine, an amino acid with similar properties. This variant demonstrated wild type-like intracellular protein abundance in a massively parallel functional assay (Matreyek KA et al. Nat Genet, 2018 06;50:874-882). In a massively parallel functional assay using a humanized yeast model, lipid phosphatase activity for this variant was wild type-like (Mighell TL et al. Am J Hum Genet, 2018 05;102:943-955). This amino acid position is not well 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 this alteration remains unclear. - |
