Hemoglobin Jamaica plain-A sickling hemoglobin with reduced oxygen affinity
Article Abstract:
Mutation in the gene encoding the beta chain of hemoglobin results in the substitution of valine for glutamic acid at position 6 and such patients are symptomatic of sickle cell anemia and hypoxemia. Structural modeling reveals destabilization of the oxy conformation as a molecular mechanism for sickling in a heterozygote at an ambient partial pressure of oxygen.

Congenital glutamine deficiency with glutamine synthetase mutations
Article Abstract:
A report is presented on two unrelated new-borns affected by congenital human glutamine synthetase deficiency with acute brain deformities, which cause multi-organ failure and neonatal mortality. Studies employing immortalized lymphocytes indicate that these mutations are related to minimized glutamine synthetase activity.

Artificial sweeteners-enhancing glycosylation to treat muscular dystrophies
Article Abstract:
A large number of genetic mutations that cause muscular dystrophies are discussed. The study shows that overexpression of a glycosyltransferase, a type of enzyme that adds sugar residues to cellular proteins, resulted in the functional rescue of dystrophic muscle cells.
