ADCK5

Chr 8

aarF domain containing kinase 5

ADCK5 encodes a predicted protein serine/threonine kinase localized to mitochondria, though its specific function and substrates remain unclear. Mutations cause autosomal recessive cerebellar ataxia, spasticity, and intellectual disability syndrome, typically presenting in childhood. The gene shows moderate constraint against loss-of-function variants.

This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.

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.
