dbSNP rs1175543698: PTEN:p.Ser294Asn (chr10-87960973-G-A) – ACMG Classification: Uncertain_significance (3 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 5P and 2B. PM1PM2PP2BP4BP6

The NM_000314.8(PTEN):c.881G>A(p.Ser294Asn) variant causes a missense change. The variant allele was found at a frequency of 0.00000124 in 1,612,674 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S294R) has been classified as Likely benign. The gene PTEN is included in the ClinGen Criteria Specification Registry.

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

Specifications for PTEN are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 4 benign, 30 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 Cowden syndrome 1, PTEN hamartoma tumor syndrome, macrocephaly-autism syndrome, glioma susceptibility 2, activated PI3K-delta syndrome, Lhermitte-Duclos disease, Bannayan-Riley-Ruvalcaba syndrome, leiomyosarcoma, Cowden disease, renal cell carcinoma, Proteus-like syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.38125414).

BP6

Variant 10-87960973-G-A is Benign according to our data. Variant chr10-87960973-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 484617.
