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]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

PM1
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 3 benign, 32 uncertain in NM_000314.8
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the PTEN gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 209 curated pathogenic missense variants (we use a threshold of 10). The gene has 22 curated benign missense variants. Gene score misZ: 3.4883 (above the threshold of 3.09). Trascript score misZ: 4.1129 (above the threshold of 3.09). GenCC associations: The gene is linked to leiomyosarcoma, renal cell carcinoma, Cowden syndrome 1, macrocephaly-autism syndrome, glioma susceptibility 2, PTEN hamartoma tumor syndrome, Cowden disease, Bannayan-Riley-Ruvalcaba syndrome, Proteus-like syndrome, Lhermitte-Duclos disease, activated PI3K-delta syndrome.
