Apolipoprotein C-II Deficiency
Sequencing of the APOC2 gene

(full coding

Lab method: Sanger sequencing

TAT: 2-4 weeks

Specimen requirements: 2-4 ml of blood with anticoagulant EDTA

300 ng DNA in TE, AE or pure sterile water at 100-250 ng/µl
The A260/A280 ratio should be 1.8-2.0. DNA sample should be run on an agarose gel as a single band, showing no degradation, alongside with a quantitative DNA marker.

Indications for genetic testing:

  1. Differential diagnosis
  2. Predictive testing
  3. Risk assessment of relatives
  4. Genetic counseling

Apolipoprotein C-II (APOC2) deficiency is a rare autosomal recessive disorder with hypertriglyceridemia resulting from impaired activation of lipoprotein lipase. Patients show severe hypertriglyceridemia and chylomicronemia and often manifest xanthomas, lipemia retinalis and pancreatitis. Hypertriglyceridemia is also an important risk factor for development of cardiovascular disease.

In most cases of APOC2 deficiency, causative mutations have been found in the protein-coding region of APOC2 gene.
