Hyper-immunoglobulin E syndromes (HIES) including compound primary immunodeficiency and nonimmunological abnormalities are characterized by extremely high serum IgE levels, eosinophilia, eczema, susceptibility to infections, distinctive facial appearance, retention of deciduous teeth, cyst-forming pneumonias, and skeletal abnormalities. Itis reported that some cases of familial HIES are relativ...

High-density lipoproteins (HDLs) are a highly heterogeneous and dynamic group of the smallest and densest lipoproteins present in the circulation. This review provides the current molecular insight into HDL metabolism led by articles describing mutations in genes that have a large affect on HDL cholesterol levels through their roles in HDL and triglyceride metabolism. Using this information fro...

Chronic diarrhea, juvenile cataracts, and tendon xanthomas, among other neurological systemic disturbances, characterize Cerebrotendinous xanthomatosis, an autosomal recessive lipid storage disease

A sibship of a brother and sister with congenital bilateral pseudoglioma is described. The most prominent abnormality was a greyish-white vascularised mass in the retrolental spaces, which was noted as early as the first weeks of life. Corneal opacities, posterior synechiae, and complicated cataracts developed within 1 to 2 years age. The sibship showed normal chromosomes and had no systemic di...
