Fetal anomalies v1.176 ERI1 Zornitza Stark Phenotypes for gene: ERI1 were changed from Spondyloepimetaphyseal dysplasia (MONDO#0100510) to Spondyloepimetaphyseal dysplasia, Guo-Salian type, MIM# 620663
Fetal anomalies v1.175 ERI1 Zornitza Stark Mode of inheritance for gene: ERI1 was changed from BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal to BIALLELIC, autosomal or pseudoautosomal
Fetal anomalies v1.174 ERI1 Zornitza Stark edited their review of gene: ERI1: Changed phenotypes: Spondyloepimetaphyseal dysplasia, Guo-Salian type, MIM# 620663; Changed mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Fetal anomalies v1.121 ERI1 Zornitza Stark Marked gene: ERI1 as ready
Fetal anomalies v1.121 ERI1 Zornitza Stark Gene: eri1 has been classified as Green List (High Evidence).
Fetal anomalies v1.121 ERI1 Zornitza Stark Classified gene: ERI1 as Green List (high evidence)
Fetal anomalies v1.121 ERI1 Zornitza Stark Gene: eri1 has been classified as Green List (High Evidence).
Fetal anomalies v1.120 ERI1 Zornitza Stark gene: ERI1 was added
gene: ERI1 was added to Fetal anomalies. Sources: Literature
Mode of inheritance for gene: ERI1 was set to BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal
Publications for gene: ERI1 were set to 37352860
Phenotypes for gene: ERI1 were set to Spondyloepimetaphyseal dysplasia (MONDO#0100510)
Review for gene: ERI1 was set to GREEN
Added comment: PMID: 37352860 - 8 individuals from 7 unrelated families
- Patients with biallelic missense show a MORE severe spondyloepimetaphyseal dysplasia, syndactyly, brachydactyly/clinodactyly/camptodactyly
- Patients with biallelic null/whole gene deletion had mild ID and digit anomalies including brachydactyly/clinodactyly/camptodactyly
- Patient chet for a missense and PTC variant has a blended phenotype with short stature, syndactyly, brachydactyly/clinodactyly/camptodactyly, mild ID and failure to thrive

- Missense variants were functionally shown to not be able to rescue 5.8S rRNA processing in KO HeLa cells
- K/O mice had neonatal lethality with growth defects, brachydactyly. Skeletal-specific K/O had mild platyspondyly, had more in keeping with patients with null variants than missense

More severe phenotype hypothesised due to "exonuclease-dead proteins may compete for the target RNA molecules with other exonucleases that have functional redundancy
with ERI1, staying bound to those RNA molecules"
