The inclusion of familial myeloid malignancies as a separate disease entity in the revised WHO classification has renewed efforts to improve the recognition and management of this group of at risk individuals. Here we report a cohort of 86 acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) families with 49 harboring germline variants in 16 previously defined loci (57%). Whole exome sequencing in a further 37 uncharacterized families (43%) allowed us to rationalize 65 new candidate loci, including genes mutated in rare hematological syndromes (ADA, GP6, IL17RA, PRF1 and SEC23B), reported in prior MDS/AML or inherited bone marrow failure series (DNAH9, NAPRT1 and SH2B3) or variants at novel loci (DHX34) that appear specific to inherited forms of myeloid malignancies. Altogether, our series of MDS/AML families offer novel insights into the etiology of myeloid malignancies and provide a framework to prioritize variants for inclusion into routine diagnostics and patient management.

Human papillomavirus (HPV) associated head and neck squamous cell carcinoma (HNSCC) has a far better prognosis than HPV negative HNSCC. Recent studies suggest that long noncoding RNA (lncRNA) moieties may play a role in HPV associated differential HNSCC prognoses. In this study, we examined differential expression of lncRNAs in HPV+ vs HPV- HNSCC using The Cancer Genome Atlas database. LncRNAs were categorized based on expression level and survival analysis. A group of eight lncRNAs was identified in which altered expression was associated with both HPV infection and better prognosis. Subsequently, genes coexpressed with these lncRNAs in HNSCC cells were sorted into corresponding co-expression modules. The lnc-IL17RA-11 coexpression module exhibited the greatest correlation with HPV infection and radiotherapy efficacy. We identified the lnc-IL17RA-11 transcription factor ER-alpha as the most likely HPV infection associated factor promoting increased lnc-IL17RA-11 levels. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analysis revealed enrichment among lnc-IL17RA-11 co-expressed genes for functions related to DNA replication and cell proliferation. These observations are consistent with a model in which HPV infection upregulates transcription factor ER-alpha, which increases levels of lnc-IL17RA-11 and coexpressed genes that promote HNSCC cell sensitivity to radiotherapy, thereby improving disease prognosis.
