Invitae RCV000810652 SCV000950877 pathogenic PTEN hamartoma tumor syndrome 2018-12-20 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 3 of the PTEN gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been observed in several individuals affected with Cowden syndrome (PMID: 21194675, 24778394, 21659347, 20600018). ClinVar contains an entry for this variant (Variation ID: 229705). Donor and acceptor splice site variants 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). For these reasons, this variant has been classified as Pathogenic.
