Description

ClinVar contains an entry for this variant (Variation ID: 40484). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (Invitae) indicates that this missense variant is expected to disrupt PTPN11 function. This missense change has been observed in individuals with clinical features of Noonan syndrome (PMID: 22465605, 25804457; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 52 of the PTPN11 protein (p.Thr52Ile).
