- Inheritance
- autosomal-dominant
- Key genes
- LPA
CircleDNA's Premium Test includes personalised reports on Elevated Lipoprotein(a) risk. See your genetic risk →
Lipoprotein(a) levels are almost entirely genetically determined with the LPA gene variants controlling levels. High Lp(a) is a major independent cardiovascular risk factor.
How Genetic Is Elevated Lipoprotein(a)?
Elevated Lipoprotein(a) has a strong genetic basis. Research estimates heritability at approximately 90%, meaning genetic factors account for the majority of variation in whether individuals develop this condition.
Key genes associated with Elevated Lipoprotein(a): LPA. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Does Family History Matter for Elevated Lipoprotein(a)?
Yes — family history is one of the strongest predictors of Elevated Lipoprotein(a). If a first-degree relative (parent, sibling, or child) has been diagnosed, your own risk may be significantly elevated. Discussing your family history with a healthcare provider or genetic counsellor is strongly recommended.
