Genes affected
PTEN (HGNC:9588): (phosphatase and tensin homolog) This gene was identified as a tumor suppressor that is mutated in a large number of cancers at high frequency. The protein encoded by this gene is a phosphatidylinositol-3,4,5-trisphosphate 3-phosphatase. It contains a tensin like domain as well as a catalytic domain similar to that of the dual specificity protein tyrosine phosphatases. Unlike most of the protein tyrosine phosphatases, this protein preferentially dephosphorylates phosphoinositide substrates. It negatively regulates intracellular levels of phosphatidylinositol-3,4,5-trisphosphate in cells and functions as a tumor suppressor by negatively regulating AKT/PKB signaling pathway. The use of a non-canonical (CUG) upstream initiation site produces a longer isoform that initiates translation with a leucine, and is thought to be preferentially associated with the mitochondrial inner membrane. This longer isoform may help regulate energy metabolism in the mitochondria. A pseudogene of this gene is found on chromosome 9. Alternative splicing and the use of multiple translation start codons results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Feb 2015]

Variant summary: PTEN c.*10delT is located in the untranslated mRNA region downstream of the termination codon. The variant allele was found at a frequency of 2.1e-05 in 238640 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.*10delT in individuals affected with Cowden Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Two clinical diagnostic laboratories and an expert panel (ClinGen PTEN Variant Curation Expert Panel) have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (VUS, n=2 to include the expert panel; likely benign, n=1). Based on the evidence outlined above, the variant was classified as uncertain significance. -

The PTEN c.*10del variant has been reported in the published literature in an individual with mild autism spectrum disorder, intellectual delay, and macrocephaly (PMID: 34268892 (2021)). The frequency of this variant in the general population, 0.000037 (4/108062 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Based on the available information, we are unable to determine the clinical significance of this variant. -
