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.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PP2

Missense variant in the STAT1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 64 curated pathogenic missense variants (we use a threshold of 10). The gene has 19 curated benign missense variants. Gene score misZ: 5.1492 (above the threshold of 3.09). Trascript score misZ: 7.0181 (above the threshold of 3.09). GenCC associations: The gene is linked to Mendelian susceptibility to mycobacterial diseases due to partial STAT1 deficiency, autoimmune enteropathy and endocrinopathy - susceptibility to chronic infections syndrome, immunodeficiency 31B.

BP4

Computational evidence support a benign effect (MetaRNN=0.3770942).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0000591 (9/152200) while in subpopulation AFR AF= 0.000217 (9/41440).

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 589 of the STAT1 protein (p.Ala589Ser). This variant is present in population databases (rs745491762, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with STAT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 424473). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬¨‚Ä†is likely to be tolerated. 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. -

This 8 year old male has a history of autism spectrum disorder, myoclonic jerks, coordination disorder, ADHD, disruptive behavior, tachycardia, joint laxity, recurrent rashes, recurrent respiratory illness, and eosinophilic esophagitis. Genetic testing to date, including exome sequencing, has not yielded a diagnosis. The p.Ala589Ser variant in STAT1 is present in the gnomAD African population at a frequency of 0.025%. Computational prediction models are inconsistent. Subsequent clinical testing showed normal neutrophil function studies and quantitative immunoglobulins. -

Collection Method: clinical testing

The c.1765G>T (p.A589S) alteration is located in exon 21 (coding exon 19) of the STAT1 gene. This alteration results from a G to T substitution at nucleotide position 1765, causing the alanine (A) at amino acid position 589 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
