Abstract:
:Approximately one in 500 individuals in Western population has autosomal dominant familial hypercholesterolemia due to mutations in the low-density lipoprotein receptor (LDLR) gene. Screening for these mutations is hampered by their large number, except in founder populations. We identified the breakpoint of the >15 kb deletion involving the LDLR gene promoter and exon 1, responsible for more than 60% of French Canadian hypercholesterolemia cases, as well as the breakpoint of the 5 kb deletion of exons 2 and 3 that accounts for an additional 5% of cases. Both deletions appear to be because of homologous recombination by unequal crossing-over between the left arms of Alu repeats. Using RepeatMasker, we determined that 55% of the LDLR gene is composed of Alu elements; thus, it is not surprising that most LDLR rearrangements involve at least one Alu. Furthermore, we developed a rapid polymerase chain reaction-based assay for the French Canadian-1 (>15 kb) and French Canadian-5 (5 kb) hypercholesterolemia alleles. Screening a representative population sample of 943 French Canadian youths whose LDL cholesterol levels were above the 50th percentile allowed us to estimate the prevalence of the >15 kb allele as 0.11% (95% confidence interval, 0.03-0.38).
