ALPK2
Chr 18alpha kinase 2
Also known as: HAK
ALPK2 encodes a protein serine/threonine kinase that regulates cardiac development and cardiomyocyte differentiation by negatively regulating Wnt/beta-catenin signaling. Mutations cause autosomal recessive cardiomyopathy with features that can include hypertrophic and dilated patterns. The gene shows moderate constraint against loss-of-function variants, and cardiac manifestations typically present in infancy or early childhood.
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.
