Variant summary
Our verdict is Pathogenic. Variant got 13 ACMG points: 13P and 0B. PM1PM2PM5PP2PP3_StrongPP5_Moderate
The NM_007315.4(STAT1):c.866A>G(p.Tyr289Cys) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic 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. Y289H) has been classified as Likely pathogenic.

Genes affected
STAT1 (HGNC:11362): (signal transducer and activator of transcription 1) The protein encoded by this gene is a member of the STAT protein family. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. The protein encoded by this gene can be activated by various ligands including interferon-alpha, interferon-gamma, EGF, PDGF and IL6. This protein mediates the expression of a variety of genes, which is thought to be important for cell viability in response to different cell stimuli and pathogens. The protein plays an important role in immune responses to viral, fungal and mycobacterial pathogens. Mutations in this gene are associated with Immunodeficiency 31B, 31A, and 31C.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Oct 26, 2022 | This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 289 of the STAT1 protein (p.Tyr289Cys). For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects STAT1 function (PMID: 27114460, 29111217). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). ClinVar contains an entry for this variant (Variation ID: 541825). This missense change has been observed in individual(s) with chronic mucocutaneous candidiasis (PMID: 27114460, 29111217; 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). - |
