Total plasma cholesterol levels in people who are homozygous for an allele that causes familial hypercholesterolemia usually range between 600 and 1,200 mg/dL. Those who are heterozygous often have levels between 300 and 400 mg/dL. The range of 100 mg/dL to 200 mg/dL is considered normal or desirable. The range of 200 mg/dL to 300 mg/dL is higher than desired but much lower than for a person who has a mutation in one or both alleles of a gene associated with familial hypercholesterolemia.
