Germline mutations in BRCA1 are associated with increased risk of breast and ovarian cancer and BRCA1 deficient tumors are exquisitely sensitive to poly (ADP-ribose) polymerase (PARP) inhibitors. Therefore, uncovering additional components of this DNA repair pathway is of extreme importance for further understanding cancer development and therapeutic vulnerabilities. Here, we identify EDC4, a known component of processing-bodies and regulator of mRNA decapping, as a member of the BRCA1-BRIP1-TOPBP1 complex. EDC4 plays a key role in homologous recombination by stimulating end resection at double-strand breaks. EDC4 deficiency leads to genome instability and hypersensitivity to DNA interstrand cross-linking drugs and PARP inhibitors. Lack-of-function mutations in EDC4 were detected in BRCA1/2-mutation-negative breast cancer cases, suggesting a role in breast cancer susceptibility. Collectively, this study recognizes EDC4 with a dual role in decapping and DNA repair whose inactivation phenocopies BRCA1 deficiency.}, language = {en} } @article{HauerPoppSchoelleretal.2018, author = {Hauer, Nadine N. and Popp, Bernt and Schoeller, Eva and Schuhmann, Sarah and Heath, Karen E. and Hisado-Oliva, Alfonso and Klinger, Patricia and Kraus, Cornelia and Trautmann, Udo and Zenker, Martin and Zweier, Christiane and Wiesener, Antje and Jamra, Rami Abou and Kunstmann, Erdmute and Wieczorek, Dagmar and Uebe, Steffen and Ferrazzi, Fulvia and B{\"u}ttner, Christian and Ekici, Arif B. and Rauch, Anita and Sticht, Heinrich and D{\"o}rr, Helmuth-G{\"u}nther and Reis, Andr{\´e} and Thiel, Christian T.}, title = {Clinical relevance of systematic phenotyping and exome sequencing in patients with short stature}, series = {Genetics in Medicine}, volume = {20}, journal = {Genetics in Medicine}, doi = {10.1038/gim.2017.159}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-227888}, pages = {630-638}, year = {2018}, abstract = {Purpose Short stature is a common condition of great concern to patients and their families. Mostly genetic in origin, the underlying cause often remains elusive due to clinical and genetic heterogeneity. Methods We systematically phenotyped 565 patients where common nongenetic causes of short stature were excluded, selected 200 representative patients for whole-exome sequencing, and analyzed the identified variants for pathogenicity and the affected genes regarding their functional relevance for growth. Results By standard targeted diagnostic and phenotype assessment, we identified a known disease cause in only 13.6\% of the 565 patients. Whole-exome sequencing in 200 patients identified additional mutations in known short-stature genes in 16.5\% of these patients who manifested only part of the symptomatology. In 15.5\% of the 200 patients our findings were of significant clinical relevance. Heterozygous carriers of recessive skeletal dysplasia alleles represented 3.5\% of the cases. Conclusion A combined approach of systematic phenotyping, targeted genetic testing, and whole-exome sequencing allows the identification of the underlying cause of short stature in at least 33\% of cases, enabling physicians to improve diagnosis, treatment, and genetic counseling. Exome sequencing significantly increases the diagnostic yield and consequently care in patients with short stature.}, language = {en} }
