title: Genetic variation and risk of chronic lymphocytic leukaemia.
abstract: Chronic lymphocytic leukaemia (CLL) is the most common form of lymphoid malignancy in Western countries, accounting for around a quarter of all leukaemias. Evidence from epidemiological and family studies have provided evidence for familial clustering of CLL compatible with inherited genetic predisposition to CLL. Direct evidence for genetic susceptibility has been provided by a recent genome wide association study of CLL which has identified common variants at 10 different loci which influence CLL risk. Here we review the current knowledge regarding the allelic architecture of susceptibility to CLL and what the currently identified risk loci are telling us regarding disease aetiology.
