Criteria Specifications for this VCEP

Evidence submitted by expert panel

PTEN VCEP

PTEN c.408T>G (p.Cys136Trp) meets criteria to be classified as pathogenic for PTEN Hamartoma Tumor syndrome in an autosomal dominant manner using modified ACMG criteria (PMID 30311380). Please see a summary of the rules and criteria codes in the “PTEN ACMG Specifications Summary” document (assertion method column). PM6_S: Assumed de novo, but without confirmation of paternity and maternity in a patient with the disease and no family history (internal laboratory contributor(s) SCV003926429.1). PM5: Missense change at an amino acid residue where a different missense change determined to be pathogenic or likely pathogenic and with equal or lesser BLOSUM62 score has been seen before (ClinVar Variation ID 189406, SCV000840468.3). PS3_M: Functional studies supportive of a damaging effect on the gene or gene product. Score of this variant = -3.54 (≤ -1.11) on a high throughput phosphatase assay (PMID 29706350). PP3: REVEL score > 0.7 (score of this variant = 0.954). 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_P: Absent in large sequenced populations (PMID 27535533).

PM2_Supporting

Absent in gnomAD v2 and v4
