indicates siblings
Mutations are in the alpha subunit of the trifunctional protein unless otherwise noted. “?” indicated alleles in which no mutations were identified following the sequencing of exons in both the alpha and beta subunits. Patients have one known mutation and clinical and biochemical evidence of LCHAD or TFP deficiency.
