CNKSR1
Chr 1connector enhancer of kinase suppressor of Ras 1
Also known as: CNK, CNK1
The protein functions as a scaffold component for receptor tyrosine kinase signaling and contains multiple protein-protein interaction domains including PDZ, PH, and SAM domains. Mutations cause X-linked intellectual disability with seizures and behavioral abnormalities. The gene shows X-linked inheritance and is not highly constrained against loss-of-function variants.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
Predictions shown for reference only — model trained on dominant genes, not applicable to AR conditions.
The Badonyi & Marsh prediction model was trained exclusively on dominant disease genes. Predictions are not reliable for genes with autosomal recessive inheritance and are shown at reduced opacity for reference only.
