Dysbetalipoproteinemia

Test description

This test consists of genotyping two polymorphisms (SNPs) in the Human Apolipoproteine E gene rs429358 (p.Cys130Arg) and rs7412 (p.Arg176Cys) by using TaqMan technology.

Methodology

The 2 variants are genotyped by a TaqMan assay in duplicate (2 independent DNA extractions) from 2 independent PCR reactions (one for each variant).

Limitations

This test will not detect all possible clinically relevant variants. A negative result does not rule out the possibility that the individual harbors a variant not included in the assay. DNA variants located in primer binding sites and rare genotyping errors can result in inaccurate diagnosis.
