英文摘要: Summary(#br)About 60–70% of hidradenoma papilliferum (HP), a benign tumour of the anogenital region, were recently described to harbour mutations in major driver genes of the PI3K/AKT/MAPK-signalling pathways. However, the underlying genetic defects of the non-mutant cases are still unknown. Using a 409 gene panel, we employed targeted next generation sequencing to investigate the mutational landscape in a cohort of seven PI3K/AKT -negative cases and five cases with known hotspot mutations in either PIK3CA or AKT1 . In total, we identified 29 mutations in 22 of 409 genes. The four cases with PIK3CA hotspot mutations carried no or only few additional mutations. The AKT1 hotspot mutated case harboured additional mutations in four genes ( SYNE1 , ADAMTS20 , EP400 and CASC5 ). At least two of...
