The disorder appears to result from a mutation in the gene for apoB-100. Extensive sequence analysis of the two alleles of one subject heterozygous for the disorder has revealed a previously unreported mutation in the codon for amino acid 3500 that results in the substitution of glutamine for arginine.

This haplotype is the same in three probands and four affected members of one family and lacks a polymorphic Xba I site whose presence has been correlated with high cholesterol levels.
