MSH: An autosomal recessively inherited disorder characterized by the accumulation of intermediate-density lipoprotein (IDL or broad-beta-lipoprotein). IDL has a CHOLESTEROL to TRIGLYCERIDES ratio greater than that of VERY-LOW-DENSITY LIPOPROTEINS. This disorder is due to mutation of APOLIPOPROTEINS E, a receptor-binding component of VLDL and CHYLOMICRONS, resulting in their reduced clearance and high plasma levels of both cholesterol and triglycerides.,CSP: rather uncommon form of familial hyperlipemia characterized by the presence of lipoproteins of abnormal composition; the main abnormal lipoproteins are called beta-VLDL and have a different apoprotein content and a higher proportion of cholesterol relative to triglyceride than normal VLDL.
