โฆ Synopsis
Three restriction fragment length polymorphisms (RFLPs) (MspI, PstI, ScrFI/BstNI) within the human porphobilinogen deaminase (PBG-D) gene have been studied in 47 unrelated patients with the autosomal dominant disorder, acute intermittent porphyria (AIP), and in 92 control subjects. Each enzyme identified a two-allele polymorphism with allele frequencies close to 0.50: however, marked linkage disequilibrium limited the number of observed haplotypes to four, of which one is uncommon. No association was detected between any haplotype and AIP.

We determined pairwise linkage disequilibria between 12 restriction fragment length polymorphism (RFLP) markers at or near the low-density lipoprotein receptor (LDLR) locus on chromosome 19~33.2-13.1 in 92 unrelated individuals. Of these 12 RFLPs, two were newly identified under a cosmid-based strat
