title: [Type IIb primary hyperlipoproteinemia. An homogenous series of 412 cases].
abstract: On the basis of a homogeneous series of 412 cases of type IIb primary hyperlipoproteinaemia, the authors compare their experience with findings in the literature. The prevalence of this type of hyperlipoproteinaemia in the general population has been underestimated at 3%. Biological diagnosis remains simple (identification of a double and distinct excess in beta and pre beta lipoproteins). Extravascular lipid deposits (gerontoxon, xanthelasma, tendon xanthomata) are not type specific. Hyperlipidaemic syndrome is rare. Above all, the importance of type IIb in atheromatous disease in the young subject now seems obvious. The mode of hereditary transmission of the familial anomaly is not certain but would appear to be often associated with a double heterozygote condition.
