Germline loss-of-function variant in the E3 ubiquitin ligase TRAF2 in a young adult patient with medulloblastoma: a case report

Abstract We identified a rare heterozygous germline loss-of-function variant in the tumor necrosis factor receptor-associated factor 2 (TRAF2) in a young adult patient diagnosed with medulloblastoma. This variant is located within the TRAF-C domain of the E3 ubiquitin ligase protein and is predicted...

description Abstract We identified a rare heterozygous germline loss-of-function variant in the tumor necrosis factor receptor-associated factor 2 (TRAF2) in a young adult patient diagnosed with medulloblastoma. This variant is located within the TRAF-C domain of the E3 ubiquitin ligase protein and is predicted to diminish the binding affinity of TRAF2 to upstream receptors and associated adaptor proteins. Integrative genomics revealed a biallelic loss of TRAF2 via partial copy-neutral loss-of-heterozygosity of 9q in the medulloblastoma genome. We further performed comparative analysis with an in-house cohort of 20 medulloblastomas sequenced using the same platform, revealing an atypical molecular profile of the TRAF2-associated medulloblastoma. Our research adds to the expanding catalog of genetic tumor syndromes that increase the susceptibility of carriers to MB.
