ERI1
Chr 8ARexoribonuclease 1
Also known as: 3'HEXO, HEXO, HXAL, SEMDGC, SEMDGS, THEX1
Enables 3'-5' exonuclease activity. Involved in maturation of 5.8S rRNA. Located in cytoplasm and nucleolus. [provided by Alliance of Genome Resources, Jul 2025]
Primary Disease Associations & Inheritance
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Tolerant to missense variation
The highest-scoring mechanism for this gene is dominant-negative.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
