===Familial component===
Familial lymphoid cancer is rare. The familial risk of lymphoma is elevated for multiple lymphoma subtypes, suggesting a shared genetic cause. However, a family history of a specific subtype is most strongly associated with risk for that subtype, indicating that these genetic factors are subtype specific. [[Genome-wide association study|Genome-wide association studies]] <!-- (GWAS) --> have successfully identified 67 [[single-nucleotide polymorphism]]s <!-- (SNPs) --> from 41 [[Locus (genetics)|loci]], most of which are subtype specific.<ref>{{cite journal | vauthors = Cerhan JR, Slager SL | title = Familial predisposition and genetic risk factors for lymphoma | journal = Blood | volume = 126 | issue = 20 | pages = 2265–73 | date = November 2015 | pmid = 26405224 | pmc = 4643002 | doi = 10.1182/blood-2015-04-537498 }}</ref>
