Active teacher and program director, academic department administration, molecular basis of monogenic hematologic disorders.
Recent work has been directed at the molecular genetics of triosephosphate isomerase (TPI) deficiency, a hereditary hemolytic anemia associated with progressive neuromuscular dysfunction. To explain the repetitive occurrence of the 104 mutation in the TPI gene in multiple apparently unrelated families throughout the world, DNA was obtained from all known families with this mutation in order to study the coinheritance of linked polymorphisms. This work has revealed an unusual haplotype, manifest in common in all of the families who carry the 104 mutation, indicating their descent from a common ancestor. Additional recent areas of inquiry include structural analysis of the TPI protein to elucidate the differing mechanisms by which the thirteen known mutations cause impaired enzyme activity and investigations into the nature of the high incidence variants involving the TPI promoter. This set of polymorphisms, which may perhaps be the highest incidence molecular markers of African lineage,are associated with moderate reduction in enzyme activity and in some instances may contribute to compound heterozygosity and clinical TPI deficiency. The finding of subjects homozygous for the -5 -8 haplotype is inconsistent with the putative role (suggested by others) of this haplotype as the cause of a null variant incompatible with life in homozygotes.
