Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 1P and 2B. PP2BS1_SupportingBP4

This summary comes from the ClinGen Evidence Repository: NM_000314.8(PTEN):c.1078A>G (p.Ser360Gly) meets criteria to be classified as likely benign for PTEN Hamartoma Tumor syndrome in an autosomal dominant manner using modified ACMG criteria (ACMG Classification Rules Specified for PTEN Variant Curation version 3.0.0). Please see a summary of the rules and criteria codes in the “PTEN ACMG Specifications Summary” document (assertion method column).PP2: PTEN is defined by the PTEN Expert Panel as a gene that has a low rate of benign missense variation and where missense variants are a common mechanism of disease.BS1_P: To be applied for variants with filtering allele frequency of 0.0000043 up to 0.000043 (0.00043% up to 0.0043%) in gnomAD. Popmax FAF of this variant=0.00001171.BP4: REVEL score < 0.5 (score of this variant=0.441).Using the Bayesian point system (PMID:29300386) for this variant with conflicting evidence: 2 benign supporting and 1 pathogenic supporting codes get (-1*2) + 1 points; total is –1 (likely benign).

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]
