Pre-B-cell leukemia homeobox 1

PBX1gene

PBX1 is a protective gene associated with supernormal coronary-artery phenotype; acts via developmental/endothelial pathways independent of atherothrombotic cascade.

Assay & specimen

Class-level default (no specific cleared assay)— generic method inferred from analyte class; confirm against a specific product insert before use.
Specimen
Whole blood — gene is not a circulating analyte; measure protein product or genotype
Collection tube
K2-EDTA whole blood (lavender-top)
Method / principle
SNP genotyping / sequencing; or immunoassay of encoded protein
Reagent / substrate
Allele-specific primers/probes (TaqMan) or NGS panel; or antibody for protein
