IL6ST encodes interleukin 6 cytokine family signal transducer (918 aa). Signal-transducing molecule. The receptor systems for IL6, LIF, OSM, CNTF, IL11, CTF1 and BSF3 can utilize IL6ST for initiating signal transmission. Highest expression in Cells Cultured fibroblasts (214.0 TPM) and Adipose Visceral Omentum (117.2 TPM).
Hyper-IgE recurrent infection syndrome 4, autosomal recessive is associated with mutations in the IL6ST gene on chromosome 5.
The IL6ST protein participates in JAK1,JAK2,(TYK2) bind IL6ST and CDH1,CDH11 promote stabilization of IL6ST protein pathways.
IL6ST is classified as a druggable target (Clinically Actionable, Druggable Genome, External Side Of Plasma Membrane, Kinase, and Tyrosine Kinase categories) with score 7.0.
Genetic testing for IL6ST is available. Testing is considered confirmatory for diagnosis.
Phenotype severity distribution: 20 always present features.
No clinical trials have been registered for hyper-IgE recurrent infection syndrome 4, autosomal recessive.
6 publications have been identified in PubMed for hyper-IgE recurrent infection syndrome 4, autosomal recessive. Research spans Review / Meta-Analysis (50%) and Case Report / Case Series (50%).
