• Skin Lesion

  Histological examination of skin lesions reveals numerous foam cells. Diagnosis is confirmed by genetic testing. [orpha.net]

• Skin Rash

  Clinical features include extensive visceral amyloid deposits, renal amyloidosis resulting in nephrotic syndrome, arterial hypertension, hepatosplenomegaly, cholestasis, petechial skin rash. There is no involvement of the nervous system. [genecards.org]

• Corneal Opacity

  Histopathological evaluations of affected corneas are not enough, and the mechanism of corneal opacity is still unclear. Case presentation A 61-year-old woman suffered from blurred vision with a corneal opacity. [bmcophthalmol.biomedcentral.com]

  CONCLUSIONS: Myriad lipid droplets in the extracellular matrix in the corneal stroma induce diffuse corneal opacity in a patient with apoA-I deficiency. [ncbi.nlm.nih.gov]

• Arcus Senilis

  In the periphery the denser deposition resembles arcus senilis. Apo A-1 deficiency was confirmed by serum analysis measures, which in our patient was 0.15 g/l (normal 1.1–2.0). [bjo.bmj.com]

  On eye examination he had significant arcus senilis. His pulses were present throughout, but somewhat diminished. He had no evidence of hepatosplenomegaly or xanthomas. [endocrine.org]

Regular cardiovascular monitoring should be offered to Apo AI deficient patients with extremely low HDL cholesterol ( Prognosis Prognosis depends on the occurrence of premature CHD and end-stage organ failure in cases with signs of amyloidosis. [orpha.net]

Etiology The disease is due to various deletions and mutations of the APOA1 gene (11q23-q24), encoding the apo A-I protein, a major constituent of HDL, that lead to decreased apo A-I production, impaired function or increased apo A-I catabolism. [orpha.net]

The underlying etiology for all clinical phenotypes of ABCA1 deficiency is the imbalance in cholesterol metabolism. [cerenis.com]

The results of many epidemiological studies show that decreased HDL-C concentrations, especially in combination with elevated LDL-C (LDL/HDL ratio > 3.5), represent a risk for coronary heart disease. [medical-genetics.de]
