AIFM1
Chr XXLRapoptosis inducing factor mitochondria associated 1
Also known as: AIF, AUNX1, CMT2D, CMTX4, COWCK, COXPD6, DFNX5, NADMR
AIFM1 encodes a mitochondrial flavoprotein that functions as an NADH oxidoreductase essential for respiratory chain biogenesis and also regulates apoptosis through caspase-independent DNA fragmentation. X-linked recessive mutations cause a spectrum of disorders including combined oxidative phosphorylation deficiency 6 (severe mitochondrial encephalomyopathy), Cowchock syndrome (X-linked Charcot-Marie-Tooth disease with neuropathy, deafness, and cognitive disability), X-linked deafness, and X-linked spondyloepimetaphyseal dysplasia with hypomyelinating leukodystrophy. The pathogenic mechanism involves loss of function, disrupting both mitochondrial respiratory chain function and cellular apoptotic regulation.

Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly LoF-intolerant (top ~10% of genes)
Moderately missense-constrained (top ~2.5%)
The highest-scoring mechanism for this gene is loss-of-function (haploinsufficiency).
Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
