ClinGen PTEN Variant Curation Expert Panel RCV000645064 SCV000840483 pathogenic PTEN hamartoma tumor syndrome 2017-12-18 reviewed by expert panel curation PTEN c.209+4_209+7delAGTA (IVS3+4_IVS3+7delAGTA) meets criteria to be classified as pathogenic for PTEN Hamartoma Tumor syndrome in an autosomal dominant manner using modified ACMG criteria (Mester et al. 2018; manuscript in preparation). Please see a summary of the rules and criteria codes in the 'PTEN ACMG Specifications Summary' document (assertion method column). PS3: RNA, mini-gene, or other assay shows impact on splicing. (PMID 28677221) PM6_S: Two probands with presumed de novo occurrence (maternity/paternity not confirmed) in a patient with the disease and no family history. (Internal laboratory contributor(s)) PM2: Absent in large sequenced populations (PMID 27535533). PP1_M: Co-segregation with disease in multiple affected family members, with 5 or 6 meioses observed. (Internal laboratory contributor(s)) PS4_P: Proband(s) with phenotype specificity score of 1-1.5. (PMID 28677221, internal laboratory contributor(s) SCV000273868.4)

Invitae RCV000645064 SCV000766805 pathogenic PTEN hamartoma tumor syndrome 2018-12-13 criteria provided, single submitter clinical testing This sequence change falls in intron 3 of the PTEN gene. It does not directly change the encoded amino acid sequence of the PTEN protein, but it affects a nucleotide within the consensus splice site of the intron. This variant is not present in population databases (ExAC no frequency). This variant has been observed in several individuals affected with, or having features consistent with, PTEN-related conditions, including a de novo observation (PMID: 10920277, 21103832, Invitae). This variant is also known as 209+1delGTAA in the literature. ClinVar contains an entry for this variant (Variation ID: 92816). Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Analysis of patient lymphocyte mRNA has shown that this variant causes aberrant splicing, resulting in skipping of exon 3  and a loss of 15 amino acid residues from the PTEN protein (PMID: 21103832). For these reasons, this variant has been classified as Pathogenic.
