We previously reported the first case of red blood cell phosphoglycerate mutase (PGAM) isozyme BB deficiency due to the homozygous point mutation cDNA 690G->A, which causes a substitution of methionine 230 by isoleucine. In the present work we analyzed the changes in glycolytic intermediates caused by this mutation. With the exception of hexose phosphates, all other intermediates were decreased. In contrast, lactate levels were increased. The methionine 230 isoleucine change did not alter the mutated PGAM levels.
