• Test Code:
    1615
  • Department:
  • Test Synonyms:
    HypoalphalipoproteinemiaCholesteryl ester Transferase DeficiencyAPOA1CETPSCRB1
  • CPT Code(s):
    81479x3
Background:

Lipid disorders comprise a group of heterogenic conditions often with overlapping clinical features such as abnormal levels of HDL, LDL, or triglycerides. High levels of HDL cholesterol in blood have been shown to atherogenic; these conditions include hypoalphalipoproteinemia and cholesteryl ester transferase deficiency.  This next-generation sequencing test is designed to detect mutations in the coding region of 3 genes associated with high HDL levels.

Reasons for Referral:

  • Abnormally high levels of HDL cholesterol.
  • Clinical presentation consistent with a lipid disorder.
  • Positive family history for High HDL (targeted testing is available if familial mutation is known).
  • Carrier testing.

Methodology:

Next generation sequencing using Illumina NextSeq 500 technology of the 3 genes associated with high HDL listed below:

High HDL Panel (3 genes): APOA1, CETP, SCARB1

Specimen Requirements:

Blood: EDTA or ACD (Solution A or B):

  • Adult: 5 mL
  • Child: 5 mL
  • Infant: 2-3 mL

A REQUISITION FORM MUST ACCOMPANY ALL SAMPLES.  Please include detailed clinical information, including ethnicity, clinical history, and family history.

Test Performed (Days):

Weekly

Turn Around Time:

8 weeks

Shipment Sensitivity Requirements:

  • Package and ship specimen to remain cold, but not frozen.
  • Ship via overnight express, using the FedEx priority overnight label provided.
  • Contact Client Services for shipping kits and instructions at (855) 535-1522.

Additional Info:

The Knight Cancer Institute at Oregon Health & Science University is a pioneer in the field of precision cancer medicine. The institute's director, Brian Druker, M.D., helped prove it was possible to shut down just the cells that enable cancer to grow. This breakthrough has made once-fatal forms of the disease manageable and transformed how cancer is treated. The OHSU Knight Cancer Institute is the only National Cancer Institute-designated Cancer Center between Sacramento and Seattle – an honor earned only by the nation's top cancer centers. It is headquarters for one of the National Cancer Institute's largest research collaboratives, SWOG, in addition to offering the latest treatments and technologies as well as hundreds of research studies and clinical trials.
