Two novel point mutations in the EGF precursor homology domain of the LDL receptor gene causing familial hypercholesterolemia.
Familial hypercholesterolemia is caused by mutations in the low density lipoprotein (LDL) receptor gene. Analysis of single-strand conformation polymorphisms of exons 10 and 11 of the LDL receptor gene from familial hypercholesterolemia heterozygotes indicated the presence of two mutations, which were characterized by DNA sequencing. One mutation (delta N466) was a 3-bp deletion in exon 10 that deletes Asn in codon 466. The other (intron 11 +1, G-->T) was a splice donor mutation at position +1 of intron 11.
