Evidence submitted by expert panel
PTEN VCEP
NM_000314.8(PTEN):c.892C>G (p.Gln298Glu) meets criteria to be classified as likely benign 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). BS1_Supporting: Filtering allele frequency of 0.00002132 (0.002132%, 4/24900 African/African American alleles) in gnomAD. BS3_Supporting: Massively parallel functional assay interrogating phosphatase activity demonstrating no statistically significant difference from wild type (PMID: 29706350). BP4: REVEL score = 0.229. 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. Variant with benign and pathogenic codes. Classification based on application of Bayesian Classification Framework (PMID: 29300386): BS1_P (-1 pt1), BS3_P (-1 pt), BP4 (-1 pt), PP2 (+1 pt) = -2 pts total (Likely Benign).
