CircleDNA's Premium Test includes personalised reports on Chronic Lymphocytic Leukemia risk. See your cancer genetic risk →
The most common adult leukaemia in Western countries. Family history increases risk ~8-fold; genome-wide studies have identified 41 risk loci.
How Genetic Is Chronic Lymphocytic Leukemia?
Chronic Lymphocytic Leukemia involves complex interactions between multiple genes and environmental factors. Heritability estimates range up to 35%, though no single gene determines outcome on its own.
Key genes associated with Chronic Lymphocytic Leukemia: IGHV TP53 ATM. 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 Chronic Lymphocytic Leukemia?
Family history can be informative for Chronic Lymphocytic Leukemia, but its predictive power is limited because many genes — each with small effects — combine with environmental influences. A family history of the condition may prompt earlier or more frequent screening.
