KANSL3

Chr 2

KAT8 regulatory NSL complex subunit 3

Also known as: KIAA1310, NSL3, Rcd1

The KANSL3 protein is a component of the NSL histone acetyltransferase complex that regulates gene transcription in both the nucleus and mitochondria, promotes cilium assembly and microtubule organization, and is essential for spindle assembly during cell division. Mutations cause autosomal dominant developmental disorders affecting multiple systems including neurological development. This gene is highly constrained against loss-of-function variants in the population, indicating that such mutations are likely to cause severe disease.

Clinical SummaryKANSL3
Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 1.00). One damaged copy is likely sufficient to cause disease.
