ANKRD16
Chr 10ankyrin repeat domain 16
ANKRD16 encodes a protein that ensures translational fidelity by preventing serine misincorporation into proteins through its interaction with alanyl-tRNA synthetase and promotion of serine-mischarged tRNA(Ala) hydrolysis. Mutations cause autosomal recessive intellectual disability with seizures and dysmorphic features, typically presenting in early childhood. The gene shows minimal constraint against loss-of-function variants, consistent with its recessive inheritance pattern.
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 gain-of-function.
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.
