GNA13 and Hodgkin's lymphoma, mixed cellularity: Furthermore, differences related to EBV status or histological subtypes are observed for PI3K signaling in pediatric HL patients by using hybrid capture-targeted next-generation sequencing of circulating cell-free DNA (ccfDNA), where MCCHL and EBV+ cases were less frequently affected by mutations in ITPKB and GNA13 genes [296].
