Novel polypyrimidine variation (IVS46: del T -39...-46) in ABCA1 causes exon skipping and contributes to HDL cholesterol deficiency in a family with premature coronary disease.

Abstract excerpt

Recent studies have implicated mutations in the ATP-binding cassette transporter A1, ABCA1, as a cause of Tangier disease (TD) and familial hypoalphalipoproteinemia (FHA). We investigated a proband with very low levels of high-density lipoprotein cholesterol (HDL-C, 6 mg/dL) and a history of premature coronary heart disease (CHD). Sequencing of the ABCA1 gene revealed 2 distinct variants. The first mutation was a...
