Is Multiple Myeloma Genetic?
Is Multiple Myeloma hereditary? Here's what the research says about inherited risk.
- Heritability
- ~15%
- Inheritance
- multifactorial
- Key genes
- CCND1,MYC,RAS
CircleDNA's Premium Test includes personalised reports on Multiple Myeloma risk. See your cancer genetic risk →
Multiple myeloma is a cancer of plasma cells. First-degree relatives have an approximately 2–3 times higher risk suggesting modest heritability.
How Genetic Is Multiple Myeloma?
Genetics plays a meaningful role in Multiple Myeloma, with heritability estimated at around 15%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Multiple Myeloma: CCND1,MYC,RAS. 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 Multiple Myeloma?
Family history does matter. Having close relatives with Multiple Myeloma can increase your personal risk, though it is not deterministic. Maintaining a healthy lifestyle and regular screening remain important regardless of family background.
Frequently Asked Questions
Is Multiple Myeloma genetic?
Genetics plays a role, but environment and lifestyle also contribute. Studies suggest heritability of approximately 15%. Key genes involved include CCND1,MYC,RAS.
Can a DNA test reveal my risk of Multiple Myeloma?
Yes — DNA tests such as CircleDNA's Premium Test include reports on Multiple Myeloma risk based on your genetic variants.
Does family history matter for Multiple Myeloma?
Family history does matter for Multiple Myeloma, though it is not deterministic — lifestyle and screening remain important regardless of family background.
Is Multiple Myeloma hereditary, meaning it's passed directly from parent to child?
Multiple Myeloma follows a multifactorial inheritance pattern in cases with a clear genetic cause, though not every case is inherited directly from a parent — some arise from new (de novo) mutations or a combination of genetic and environmental factors.
