IFI44
Chr 1interferon induced protein 44
Also known as: MTAP44, TLDC5, p44
The IFI44 protein aggregates to form microtubular structures and is predicted to be involved in cellular immune responses to viral and bacterial infections. This gene is not constrained against loss-of-function variants (LOEUF 1.496), and no established Mendelian diseases have been definitively linked to IFI44 mutations in the current literature.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Tolerant to missense variation
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.
