title: Human lactate dehydrogenase-B processed pseudogene: nucleotide sequence analysis and assignment to the X-chromosome.
abstract: Two human genomic clones containing the lactate dehydrogenase-B processed pseudogene were isolated from two patients deficient in lactate dehydrogenase-B isozyme. The sequences of 3,287 nucleotides, including the pseudogenes and its flanking regions, from both clones were found to be identical except for three differences in the pseudogenes. The sequences of 1,286 nucleotides from these two pseudogenes exhibited 93% homology with the cDNA sequence of the lactate dehydrogenase-B functional gene, and the pseudogene contained 75/76 base substitutions, 11/12 single-base deletions, and 5 single-base insertions. This pseudogene was mapped to the x-chromosome by dot-blot analysis using a probe for the pseudogene or its 5' flanking sequence.
