1Mitochondrial Respiration Under a Permeabilized-Cell Assay
Digitonin-permeabilized HeLa cells are suspended in a respirometer at 37 °C. You add pyruvate plus malate (state 2), then ADP (state 3), then oligomycin, then FCCP, then antimycin A.

In a consanguineous family, first-cousin parents are unaffected and have three children: two sons with developmental delay, seizures, and low cerebrospinal fluid glucose, and one unaffected daughter. Whole-exome sequencing identifies a homozygous missense variant, c.1234G A (p.Gly412Arg), in a gene linked to autosomal recessive neurodevelopmental disease.
