The variant received -5 classification points (ACMG Germline Pathogenicity v2019). PM2BP4_StrongBP6_ModerateBP7

The NM_000314.8(PTEN):c.390A>T (p.Arg130Arg) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★). 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.

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]

Classification according to ACMG Germline Pathogenicity v2019

Classification was made for transcript:

Our verdict: Likely_benign. The variant received -5 points.

PM2Absent/extremely low in population databases
Absent from gnomAD (AD/XL gene) — PM2; Absent from gnomAD at well-covered site (MOI: AD+AR) (base 0.0001, raised to 0.000104 by highest known P/LP ClinVar AF 0.000104) — PM2 moderate.
BP4Computational evidence suggests no impact
Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Strong).
BP6Reputable source reports benign
ClinVar 1-star benign — moderate (BP6); ClinVar germline classification: Benign/Likely Benign, 1 star(s).
BP7Synonymous variant, no splicing impact
Synonymous variant at non-conserved position with no predicted splicing impact (BP7); Synonymous at non-conserved position, no splicing concern — benign (BP7).
