" /> Hypertriglyceridemia 1 - CISMeF





Preferred Label : Hypertriglyceridemia 1;

Symbol : HYTG1;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Hypertriglyceridemia, familial;

Description : Most individuals with familial hypertriglyceridemia have a hyperlipoproteinemia IV (144600) phenotype. Relatives of affected persons (ascertained in a study of survivors of coronary occlusion) were found to have normal cholesterol distribution and bimodal triglyceride distribution (Goldstein et al., 1973). Hypertriglyceridemia is not completely expressed in affected children. - Genetic Heterogeneity of Hypertriglyceridemia Hypertriglyceridemia has many causes but, whatever its cause, there is evidence for its role as a coronary heart disease risk factor. Hypertriglyceridemia is commonly found in individuals with type II diabetes mellitus (125853). Several genetic bases for hypertriglyceridemia have been identified. Familial combined hyperlipidemia (HYPLIP1; 602491) is due to variation in the USF1 gene (191523) on chromosome 1q21-q23. Some mutations in the ABCA1 gene (600046) caused Tangier disease (205400), whereas others caused a mild disorder called type II familial high density lipoprotein deficiency, or hypoalphalipoproteinemia (604091). Both disorders are associated with hypertriglyceridemia.;

Inheritance : Autosomal dominant;

Prefixed ID : #145750;
