Variant summary
Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM1PM2PM5PP2PP3_Moderate
The NM_000314.8(PTEN):c.472G>T(p.Val158Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,152 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V158A) has been classified as Uncertain significance.

PTEN hamartoma tumor syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jul 14, 2021 | This variant has been observed in individual(s) with multiple primary tumors (PMID: 10807691). This variant has been reported to have conflicting or insufficient data to determine the effect on PTEN protein function (PMID: 10807691). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with leucine at codon 158 of the PTEN protein (p.Val158Leu). The valine residue is highly conserved and there is a small physicochemical difference between valine and leucine. - |
