Tangier disease is an extremely rare autosomal recessive monogenic disorder caused by mutations in the ATP binding cassette transporter A1 gene (ABCA1). It is characterized by severe deficiency or absence of high-density lipoprotein cholesterol (HDL-C) and apolipoprotein A-1 (ApoA1), with highly variable clinical presentations depending on cholesterol accumulation in macrophages across different tissues. We report a case of a 47-year-old man with very low HDL-C and very high triglyceride levels, initially attributed to the patient's metabolic syndrome, alcohol abuse, and splenomegaly.
