Germline Mutation in KIF1Bβ Gene Associated with Loss of Heterozygosity: Usefulness of Next-Generation Sequencing in the Genetic Screening of Patients with Pheochromocytoma

Figure 3

Representative ultrastructural micrographs of a pheochromocytoma bearing the KIF1Bβ mutation (a, b) in comparison with a wild-type tumor (c). Gene mutation is associated with the occurrence of numerous swollen mitochondria (dashed arrows) with reduction of cristae and matrix clearing. Several autophagic vacuoles (black arrows) containing remnants of organelles, including mitochondria (a) can also be seen. Magnification: x12,000.
