ERI1 encodes exoribonuclease 1 (349 aa). RNA exonuclease that binds to the 3'-end of histone mRNAs and degrades them, suggesting that it plays an essential role in histone mRNA decay after replication. Highest expression in Cells Cultured fibroblasts (13.9 TPM) and Testis (12.1 TPM).
Spondyloepimetaphyseal dysplasia, Guo-Campeau type is associated with mutations in the ERI1 gene on chromosome 8.
ERI1 is classified as a druggable target with score 0.0.
Genetic testing for ERI1 is available. Testing is considered confirmatory for diagnosis.
Phenotype severity distribution: 51 always present features, 3 common features.
No clinical trials have been registered for spondyloepimetaphyseal dysplasia, Guo-Campeau type.
1 publication has been identified in PubMed for spondyloepimetaphyseal dysplasia, Guo-Campeau type. Research spans Review / Meta-Analysis (100%).
