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]

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.741dupA pathogenic mutation, located in coding exon 7 of the PTEN gene, results from a duplication of A at nucleotide position 741, causing a translational frameshift with a predicted alternate stop codon (p.P248Tfs*5). This alteration has been reported in multiple individuals with personal history consistent with PTEN Hamartoma Tumor Syndrome (Ha JW. Clin Endosc, 2013 Jan;46:85-90; Plamper M et al. Cancers (Basel), 2019 Jul;11; Rosenfeld EH et al. J Pediatr Gastroenterol Nutr, 2019 Feb;68:e35-e37). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -
