HDAC11
Chr 3histone deacetylase 11
Also known as: HD11
This gene encodes a class IV histone deacetylase that removes acetyl groups from core histones H2A, H2B, H3, and H4, serving as an epigenetic regulator of transcriptional repression and developmental processes. Mutations in HDAC11 cause autosomal recessive neurodevelopmental disorder with seizures and brain atrophy, typically presenting in early childhood. The gene shows moderate constraint against loss-of-function variants, consistent with its role in essential cellular processes.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Typical tolerance to LoF variation
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.
