ZRANB2
Chr 1zinc finger RANBP2-type containing 2
Also known as: ZIS, ZIS1, ZIS2, ZNF265
ZRANB2 encodes a splice factor that binds single-stranded RNA and is required for alternative splicing of specific transcripts, particularly those containing the consensus sequence 5'-AGGUAA-3'. The gene is highly constrained against loss-of-function variants (pLI = 1.0, LOEUF = 0.18), but specific diseases associated with ZRANB2 mutations have not yet been established in the clinical literature. Given its essential role in RNA splicing and extreme constraint metrics, pathogenic variants would likely cause developmental abnormalities, though the inheritance pattern and clinical phenotype remain to be characterized.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly LoF-intolerant (top ~10% of genes)
Mild missense constraint
The highest-scoring mechanism for this gene is loss-of-function (haploinsufficiency).
Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
