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]

This variant is considered benign. This variant has been observed at a population frequency that is significantly greater than expected given the associated disease prevalence and penetrance. Homozygosity has been confirmed in one or more individuals. As homozygosity for pathogenic variants in this gene is generally assumed to result in embryonic lethality, this variant is unlikely to be pathogenic. -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

The PTEN c.-9C>G variant was identified in 137 of 2170 proband chromosomes (frequency: 0.06) from individuals or families with Li-Fraumeni syndrome, ESCC, GCA, breast, thyroid cancer (Ge 2008, Ng 2014, Yang 2013). The variant was also identified in the following databases: dbSNP (ID: rs11202592) as With other allele, ClinVar (classified as benign by Ambry Genetics, Invitae, PreventionGenetics, Counsyl, Color Genomics; classified as likely benign by Illumina), Clinvitae (classified as benign by ClinVar), and the Zhejiang Colon Cancer Database. The variant was not identified in the LOVD 3.0 database. The variant was identified in control databases in 1000 (24 homozygous) of 277238 chromosomes at a frequency of 0.0036 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Consortium Feb 27, 2017). The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. The case study by Akouchekian (2015) suggests the substitution of C to G in the 5′UTR results in a recovery of the periodical occurrence of the G residue (gtcccagacATGa), which closely matches the consensus sequence that helps ribosomes stay in-frame during translation, and it may affect the expression of the PTEN gene. The population-based case-control study by Ge (2008) identify the overall PTEN –9C/G genotype distributions in ESCC, GCA patients were not significantly different from that in healthy controls (χ2 = 0.19 and 0.42; P = 0.66 and 0.52, respectively). In addition, in vitro cell transfection showed that the variant (–9G) allele resulted in a significantly higher level of protein expression compared with the wild-type allele (–9C) (Ishihara 2003). In summary, based on the above information this variant meets our laboratory's criteria to be classified as benign. -
