Evidence submitted by expert panel

PTEN VCEP

NM_000314.8(PTEN):c.46T>C (p.Tyr16His) is currently classified as a variant of uncertain significance for PTEN Hamartoma Tumor syndrome in an autosomal dominant manner using modified ACMG criteria (ACMG Classification Rules Specified for PTEN Variant Curation version 3.0.0). Please see a summary of the rules and criteria codes in the “PTEN ACMG Specifications Summary” document (assertion method column). PM2_P: This variant is absent from gnomAD database. PP2: PTEN is defined by the PTEN Expert Panel as a gene that has a low rate of benign missense variation and where missense variants are a common mechanism of disease. PP3: REVEL score > 0.7 (score of this variant = 0.866) BS3_P: Well-established functional studies show no deleterious effect: Phosphatase activity >0 (score of this variant = 0.34095) per Mighell et al. 2018 (PMID: 29706350). Using the Bayesian point system (PMID: 29300386) for this variant with conflicting evidence: 1 benign supporting and 3 pathogenic supporting codes get -1 + (1*3) points; total is 2 (Uncertain significance).

BS3_Supporting

Well-established functional studies show no deleterious effect: Phosphatase activity >0 (score of this variant = 0.34095) per Mighell et al. 2018 (PMID: 29706350).

PIP3 phosphatase activity assays in yeast showed no obvious differences of PTEN PIP3-phosphatase activity between wildtype and p.Tyr16His variant. Cum_socre: 0.34095 PubMed:29706350

The cellular locations of PTEN protein in COS-7 cell assay and PIP3 phosphatase activity assays in yeast showed no obvious differences of PTEN PIP3-phosphatase activity between wildtype and p.Tyr16His variant. PubMed:29706633

PP3

REVEL score > 0.7 (score of this variant = 0.866)

PP2

PTEN is defined by the PTEN Expert Panel as a gene that has a low rate of benign missense variation and where missense variants are a common mechanism of disease.

PM2_Supporting

This variant is absent from gnomAD v2.1.1 (PM2).
