Invitae RCV001236483 SCV001409208 uncertain significance PTEN hamartoma tumor syndrome 2023-04-29 criteria provided, single submitter clinical testing This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 65 of the PTEN protein (p.Tyr65Cys). 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. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on PTEN function (PMID: 19457929, 20926450, 31006514, 32350270). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt PTEN protein function. ClinVar contains an entry for this variant (Variation ID: 962600). This missense change has been observed in individual(s) with clinical features of PTEN-related conditions (PMID: 24375884). This variant is not present in population databases (gnomAD no frequency).
