Hyperbetalipoproteinemia, a syndrome characterized by an increased level of low density lipoproteins and their associated lipid components, is frequently manifested externally by xantholasma and xanthomata tendinosum and/or xanthoma tuberosum. A large kindred of 57 living members was extensively investigated and is described in detail in view of the rarity of such observations. Concerning the inheritance of such familial hypercholesterolemia, this study lends support to Wilkinson's views suggesting that severe generalized xanthomatosis is evidence of homozygosity.
