Variant summary
Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1PM2PM5PP2PP3_ModeratePP5_Moderate
The NM_139276.3(STAT3):c.986T>A(p.Met329Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M329R) has been classified as Likely pathogenic.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Sep 07, 2022 | ClinVar contains an entry for this variant (Variation ID: 476197). This missense change has been observed in individual(s) with STAT3-related conditions (PMID: 33365035, 33717144; Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces methionine, which is neutral and non-polar, with lysine, which is basic and polar, at codon 329 of the STAT3 protein (p.Met329Lys). 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 STAT3 protein function. For these reasons, this variant has been classified as Pathogenic. - |
