IL11RA encodes interleukin 11 receptor subunit alpha (422 aa). Receptor for interleukin-11 (IL11). The receptor systems for IL6, LIF, OSM, CNTF, IL11 and CT1 can utilize IL6ST for initiating signal transmission. Highest expression in Artery Aorta (80.6 TPM) and Cervix Ectocervix (74.6 TPM).
Craniosynostosis and dental anomalies is caused by mutations in the IL11RA gene on chromosome 9.
IL11RA is classified as a druggable target (Druggable Genome and External Side Of Plasma Membrane categories) with score 26.1.
Genetic testing for IL11RA is available. Testing is considered confirmatory for diagnosis.
Biomarker and diagnostic research for craniosynostosis and dental anomalies has been reported in the published literature.
Phenotype severity distribution: 10 always present features, 2 very common features, 25 common features.
Estimated prevalence: <1 in 1,000,000 (VERY_RARE).
No clinical trials have been registered for craniosynostosis and dental anomalies.
122 publications have been identified in PubMed for craniosynostosis and dental anomalies. Research spans Review / Meta-Analysis (44%), Epidemiology / Natural History (22%), and Case Report / Case Series (20%).
