Familial hypobetalipoproteinemia (FHBL) is a genetic disorder characterized by low levels of apoB-100 and LDL cholesterol. Truncation-producing mutations of apoB (chromosome 2) are among several potential causes of FHBL in patients. Ten new families with FHBL linked to chromosome 2 were identified.
Novel mutations of APOB cause apoB truncations undetectable in plasma and familial hypobetalipoproteinemia

Familial hypobetalipoproteinemia (FHBL) is a rare codominant disorder of lipoprotein metabolism characterized by low levels of low-density lipoprotein (LDL) cholesterol and apolipoprotein (apo) B. Heterozygotes for FHBL have less-than-half normal LDL-cholesterol and apoB concentrations, whereas homo
We report a 49-member four-generation kindred in which 11 members express familial hypobetalipoproteinemia (FHBL). In other kindreds, various truncated apoB species cosegregate with the FHBL phenotype. In contrast, no truncated apoB proteins were found by immunoblotting of plasma samples in this kin
