NMT2
Chr 10N-myristoyltransferase 2
This gene encodes N-myristoyltransferase 2, which catalyzes the addition of myristoyl groups to the N-terminal glycine residues of signaling proteins, a lipid modification essential for proper protein localization and membrane association. Mutations cause autosomal recessive developmental delay, seizures, and hypotonia with early childhood onset. The gene is highly constrained against loss-of-function variants, indicating that complete loss of function is likely incompatible with normal development.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
More LoF-intolerant than ~75% of genes
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.
