Aside from these 5 samples, the highest number of mutations in a single sample across all diagnoses in our dataset was in a meningioma with 5 heteroplasmic mutations (sample ID BS_2W200YK5) which showed missense mutations in MT-CO1, MT-ND3, and MT-ND4L as well as an RNR1 mutation and a D-loop mutation. This evidence concerns the gene NR4A2 and meningioma.
