Although CDKN2A aberrations are common in DLBCL, this gene is predominantly affected by copy number alterations. One study found that deletions of the CDKN2A locus occur in about one-third of DLBCL patients.1 The mutation pattern in DLBCL and FL implies the preferential accumulation of inactivating mutations . This gene has some recurrent sites of mutations (hotspots) with the most common mutation causing a truncation at codon 80 (R80*).
