The NM_000314.8(PTEN):c.388C>G (p.Arg130Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The gene PTEN is a tumor suppressor gene (CancerMine: 876 TSG, 281 oncogene, 265 driver citations). The gene PTEN is a known oncogene (CancerMine: 876 TSG, 281 oncogene, 265 driver citations). The gene PTEN is a cancer driver gene (CancerMine: 876 TSG, 281 oncogene, 265 driver citations). The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. In-silico predictor (REVEL) classifies this variant as likely damaging/oncogenic. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Pathogenic/Likely Pathogenic (★★★). ClinVar reports functional evidence for this variant: "SCV000930114: Phosphatase activity <50% of wild type (PMID 10866302, PMID 21828076, PMID 29706350)" and additional evidence is available in ClinVar. A different missense at the same amino acid position has been reported as Pathogenic/Likely Pathogenic in ClinVar: p.R130L: Pathogenic/Likely_pathogenic (ClinVar VariationId 376509, 2 stars) Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.R130?: Uncertain_significance (ClinVar VariationId 2687576, 0 stars); p.R130?: Uncertain_significance (ClinVar VariationId 2687578, 0 stars); p.R130= (synonymous): Benign/Likely_benign (ClinVar VariationId 1735874, 2 stars); p.R130= (synonymous): Benign/Likely_benign (ClinVar VariationId 3903832, 2 stars); p.R130= (synonymous): Likely_benign (ClinVar VariationId 1648484, 1 star) This exact variant is established as oncogenic in: ClinVar, CGI (Cancer Genome Interpreter). The variant position is a cancer hotspot (cancerhotspots.org): 239 samples carry this exact amino acid change out of 1912 samples with a variant at this residue. The variant has been observed in cBioPortal in 803 samples across 53 studies and 44 cancer types; somatic enrichment level: MODERATE (Observed in many cases across multiple studies/cancer contexts.). This exact variant is curated in the UniProt human variants database as Uncertain Significance.

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]
