Researchers at St. Jude Children&rsquo;s Research Hospital, the European Molecular Biology Laboratory, and the German Cancer Research Center have identified a novel predisposition gene, ELP1, in the subgroup of a common pediatric <a href="https://www.docwirenews.com/docwire-pick/hem-onc-picks/brain-tumor-organoids-key-in-treating-glioblastomas/">brain tumor</a>, medulloblastoma, according to a study published in Nature.The team looked at all protein-coding genes (the exome) in more than 1,000 patients with medulloblastoma. The researchers compared their medulloblastoma findings to more than 118,000 exomes from several databases of individuals without cancer. According to the results, ELP1 is abnormally mutated in the germline DNA of 14-15% of children with SHH medulloblastoma.Moreover, with the addition of ELP1 to the list of known cancer predisposition genes, the researchers showed that at least 40% of pediatric SHH medulloblastoma is driven by an inherited abnormality. ELP1 mutations occur at more than double the rate of any other previously acknowledged cancer predisposition gene in SHH medulloblastoma.<blockquote class="twitter-tweet" data-width="500" data-dnt="true">
