Leukaemia encompasses cancers of blood-forming tissues. Certain forms have identifiable hereditary components and familial clustering.
How Genetic Is Leukaemia?
Genetics plays a meaningful role in Leukaemia, with heritability estimated at around 30%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Leukaemia: BCR-ABL1,TP53,BRCA1. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
