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 | GeneDx | May 03, 2022 | Reported in unrelated individuals with autosomal dominant STAT1-related immunodeficiency in the published literature (van de Veerdonk et al., 2011; Mizoguchi et al., 2014; Depner et al., 2016; Breuer et al., 2017); Published functional studies demonstrate that A267V leads to increased STAT1 phosphorylation, increased DNA binding and transactivation, and impaired STAT3 activity (Sampaio et al., 2013; Zheng et al., 2015); Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 28161409, 26494717, 26255980, 28815025, 28427548, 26604104, 21714643, 30187709, 32146551, 32888943, 24343863, 23541320) - |

Immunodeficiency 31B;C3279990:Autoimmune enteropathy and endocrinopathy - susceptibility to chronic infections syndrome;C4013950:Mendelian susceptibility to mycobacterial diseases due to partial STAT1 deficiency Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 18, 2023 | This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 267 of the STAT1 protein (p.Ala267Val). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with autosomal dominant chronic mucocutaneous candidiasis (PMID: 21714643, 23709754, 24343863, 26255980, 26494717, 26604104). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 30084). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects STAT1 function (PMID: 23541320, 26255980). For these reasons, this variant has been classified as Pathogenic. - |
Mendelian susceptibility to mycobacterial diseases due to partial STAT1 deficiency Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Baylor Genetics | Sep 12, 2018 | This variant was determined to be pathogenic according to ACMG Guidelines, 2015 [PMID:25741868]. This variant has been previously reported as a pathogenic variant with gain-of-function disease mechanisms [PMID 21714643, 28427548, 28161409, 26604104, 28815025, 24343863, 26494717, 23541320, 26255980] - |
Chronic mucocutaneous candidiasis Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | May 04, 2018 | The p.Ala267Val variant in STAT1 has been reported in >10 individuals with chron ic mucocutaneous candidiasis (CMC) and segregated with disease in 16 individuals from 9 families (Liu 2011, van de Veerdonk 2011, Sampaio 2013, Mizoguchi 2014, Nielsen 2015, Zheng 2015, Depner 2016, Breuer 2017, Dadak 2017). It was absent f rom large population studies. Additionally, in vitro functional studies support a pathogenic role (Sampaio 2013, Mizoguchi 2014, Zheng 2015). In summary, the p. Ala267Val variant meets criteria to be classified as pathogenic for CMC in an au tosomal dominant manner. ACMG/AMP Criteria applied: PP1_Strong; PM2; PS4_Moderat e; PP3; PS3_Supporting. - |
