Familial Hypercholesterolemia also known as FM, is a disease of extremely high cholesterol levels beginning early in gestation. It is passed along from family member to family member through a genetic mutation. Most commonly on chromosome 19. Many other chromosomes have now been identified as causing familial hypercholesterolemia such as (apo) B-100 (FDB, OMIM 144010). APOB gene (OMIM 107730), and FDB mutations such as Arg3527GlN. FM is an autosomal dominant trait.
Individual can inherit either 1 gene from 1 parent, (heterozygous) or two genes from both parents (homozygous). Those born with two defective genes tend to have a more severe form of FM. In the homozygous form of FM, symptoms and complications affect these individuals at a much earlier age, even as early as adolescence and younger.

Heart attack and death may occur before age
