PARP11
Chr 12poly(ADP-ribose) polymerase family member 11
Also known as: ARTD11, C12orf6, MIB006
PARP11 encodes a mono-ADP-ribosyltransferase that modifies target proteins and regulates interferon signaling and nuclear envelope stability. Mutations cause autosomal recessive intellectual disability with microcephaly and seizures, typically presenting in infancy. The gene is highly intolerant to loss-of-function variants, suggesting mutations likely result in severe functional impairment.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
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.
