TERT and granulosa cell tumor: The genomic landscape of juvenile granulosa cell tumors has been recently studied, highlighting several other recurrent gene variants in different gene categories: epigenetic modifiers (KMT2C [52%], ARID1A [39%], KMT2D [35%]), homologous recombination (BRCA2 [35%], ATM [26%], BRCA1 [23%]), mismatch repair (POLE [23%], MLH1 [19%], MSH6 [10%]), and telomere elongation (TERT variant in 19% of tumors, TERT rearrangement in 13%) [143].
