  1. A novel PKLR gene mutation was identified in members of a Chinese family with hemolytic anemia. PMID: 29349879
  2. Results show that different residues contribute to the two allosteric functions: regulation by the activator fructose-1,6-bisphosphate (Fru-1,6-BP) and alanine, the inhibitor. Only a small fraction of mutated residues perturbed inhibition by alanine.
