For patient 10 in Table 2, diagnosed with an IDH-wildtype anaplastic astrocytoma, a p.I1398T change in SETD2 was found; however, this may represent a benign single nucleotide polymorphism as it is seen at > 0.1% frequency in the Ashkenazi Jewish population (http://gnomad.broadinstitute.org/) [12]. The gene discussed is IDH1; the disease is anaplastic astrocytoma.
