Labcorp Genetics (formerly Invitae), Labcorp RCV005207012 SCV005843603 likely pathogenic PTEN hamartoma tumor syndrome 2025-01-19 criteria provided, single submitter clinical testing This sequence change affects a splice site in intron 1 of the PTEN gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in PTEN are known to be pathogenic (PMID: 9467011, 21194675). Information on the frequency of this variant in the gnomAD database is not available, as this variant may be reported differently in the database. This variant has not been reported in the literature in individuals affected with PTEN-related conditions. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
