abstract = {To decipher the mutational pattern of primary CNS lymphoma
(PCNSL), we performed whole-exome sequencing to a median
coverage of 103 × followed by mutation verification in 9
PCNSL and validation using Sanger sequencing in 22 PCNSL. We
identified a median of 202 (range: 139-251) potentially
somatic single nucleotide variants (SNV) and 14 small indels
(range: 7-22) with potentially protein-changing features per
PCNSL. Mutations affected the B-cell receptor, toll-like
receptor, and NF-κB and genes involved in chromatin
structure and modifications, cell-cycle regulation, and
immune recognition. A median of $22.2\%$ (range:
$20.0-24.7\%)$ of somatic SNVs in 9 PCNSL overlaps with the
RGYW motif targeted by somatic hypermutation (SHM); a median
of $7.9\%$ (range: $6.2-12.6\%)$ affects its hotspot
position suggesting a major impact of SHM on PCNSL
pathogenesis. In addition to the well-known targets of
aberrant SHM (aSHM) (PIM1), our data suggest new targets of
aSHM (KLHL14, OSBPL10, and SUSD2). Among the four most
frequently mutated genes was ODZ4 showing protein-changing
mutations in 4/9 PCNSL. Together with mutations affecting
CSMD2, CSMD3, and PTPRD, these findings may suggest that
alterations in genes having a role in CNS development may
facilitate diffuse large B-cell lymphoma manifestation in
the CNS. This may point to intriguing mechanisms of CNS
tropism in PCNSL.},
