EIF4E1B
Chr 5eukaryotic translation initiation factor 4E family member 1B
The protein recognizes and binds the 7-methylguanosine mRNA cap and facilitates ribosome binding by unwinding mRNA secondary structures during protein synthesis initiation. Mutations in this gene have not yet been definitively associated with human disease. The gene shows tolerance to loss-of-function variants (LOEUF 1.303), suggesting it may not be essential for normal development.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
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.
