IDH2 and TP53 mutations are correlated with gliomagenesis in a patient with Maffucci syndrome

Kunihiko Moriya et al. Cancer Sci. 2014 Mar.

Abstract

We report on a 24-year-old woman who was diagnosed as having Maffucci syndrome with anaplastic astrocytoma. We analyzed the IDH1 and IDH2 mutations of enchondroma, hemangioma and anaplastic astrocytoma tissues and the same somatic mosaic mutation in IDH2 gene was identified in all these tissues. In addition, we identified additional mutation of the TP53 gene in anaplastic astrocytoma tissue but not in other benign tumors. This is the first report of the detection of an identical IDH2 mutation in multiple tissues and TP53 mutation in anaplastic astrocytoma in a patient with Maffucci syndrome. This case is unique and supports the IDH2-dependent genetic pathway and second-hit model for gliomagenesis.

Keywords: Anaplastic astrocytoma; IDH2 mutation; Maffucci syndrome; TP53; gliomagenesis.

Mutational analysis of IDH2. (a) Direct DNA sequencing of IDH2 was performed in the enchondroma, hemangioma and astrocytoma tissues. (b) PCR products of IDH2 were subcloned into pCR4-TOPO vectors, and each clone was sequenced to confirm the heterogeneous mutation of IDH2.
