| Abstract | Clinical familial hypercholesterolemia has been shown to result from mutations in 2 genes, the low density lipoprotein (LDL) receptor on chromosome 19 and apolipoprotein B on chromosome 2. However, we have recently described a Utah pedigree in which linkage to both genes was clearly excluded. A multipoint linkage analysis of 583 markers genotyped on 31 (18 affected) members of this pedigree was undertaken to localize a genetic region that may harbor a third gene that could result in clinical familial hypercholesterolemia. A multipoint log of the odds score of 6.8 was obtained for markers on 1p32. Haplotype carriers and affected status are completely concordant (18/18 persons). The phenotype is also expressed in young children (ages 4 and 9). Specific recombinant individuals in the pedigree restrict the region of linkage to an approximately 17 cM interval between polymorphic markers D1S2130 and D1S1596. This region appears to overlap the region found linked to severe hypercholesterolemia in French and Spanish families. The identification of the gene in this region may provide important pathophysiological insights into new mechanisms that may lead to highly elevated LDL cholesterol and other associated dyslipidemic phenotypes. |
