CAMK1D
Chr 10calcium/calmodulin dependent protein kinase ID
Also known as: CKLiK, CaM-K1, CaMKID
The protein is a calcium/calmodulin-dependent serine/threonine kinase that activates CREB-dependent gene transcription and regulates granulocyte function and dendritic growth in hippocampal neurons. Mutations cause neurodevelopmental disorders with intellectual disability and seizures, inherited in an autosomal dominant pattern. This gene is highly constrained against loss-of-function mutations, indicating it is essential for normal cellular function.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly LoF-intolerant (top ~10% of genes)
Moderately missense-constrained (top ~2.5%)
This gene has evidence for multiple mechanisms of pathogenicity (loss-of-function and gain-of-function). The Badonyi & Marsh model scores gain-of-function highest among its predictions, but genomic evidence (constraint, ClinVar variant spectrum, and literature) most strongly supports loss-of-function (haploinsufficiency). 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.
Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
