Traditionally, pedigrees are used to shed light on the latter only, while here we discuss the application of polygenic risk scores to also highlight patterns of common genetic risk. We analyze polygenic risk scores for psychiatric disorders in a large pedigree (n ~ 260) in which 30\% of family members suffer from major depressive disorder or bipolar disorder. Studying patterns of assortative mating and anticipation, it appears increased polygenic risk is contributed by affected individuals who married into the family, resulting in an increasing genetic risk over generations. This may explain the observation of anticipation in mood disorders, whereby onset is earlier and the severity increases over the generations of a family. Joint analyses of rare and common variation may be a powerful way to understand the familial genetics of psychiatric disorders.}, language = {en} } @article{DekkerDiekstraPulitetal.2019, author = {Dekker, Annelot M. and Diekstra, Frank P. and Pulit, Sara L. and Tazelaar, Gijs H.

Genetic association studies have established ALS as a multifactorial disease with heritability estimated at ~61\%, and recent studies show a prominent role for rare variation in its genetic architecture. To identify rare variants associated with disease onset we performed exome array genotyping in 4,244 cases and 3,106 controls from European cohorts. In this largest exome-wide study of rare variants in ALS to date, we performed single-variant association testing, gene-based burden, and exome-wide individual set-unique burden (ISUB) testing to identify single or aggregated rare variation that modifies disease risk. In single-variant testing no variants reached exome-wide significance, likely due to limited statistical power. Gene-based burden testing of rare non-synonymous and loss-of-function variants showed NEK1 as the top associated gene. ISUB analysis did not show an increased exome-wide burden of deleterious variants in patients, possibly suggesting a more region-specific role for rare variation. Complete summary statistics are released publicly. This study did not implicate new risk loci, emphasizing the immediate need for future large-scale collaborations in ALS that will expand available sample sizes, increase genome coverage, and improve our ability to detect rare variants associated to ALS.}, language = {en} } @article{DiehlSchmidLicataGoldhardtetal.2019, author = {Diehl-Schmid, Janine and Licata, Abigail and Goldhardt, Oliver and F{\"o}rstl, Hans and Yakushew, Igor and Otto, Markus and Anderl-Straub, Sarah and Beer, Ambros and Ludolph, Albert Christian and Landwehrmeyer, Georg Bernhard and Levin, Johannes and Danek, Adrian and Fliessbach, Klaus and Spottke, Annika and Fassbender, Klaus and Lyros, Epameinondas and Prudlo, Johannes and Krause, Bernd Joachim and Volk, Alexander and Edbauer, Dieter and Schroeter, Matthias Leopold and Drzezga, Alexander and Kornhuber, Johannes and Lauer, Martin and Grimmer, Timo}, title = {FDG-PET underscores the key role of the thalamus in frontotemporal lobar degeneration caused by C9ORF72 mutations}, series = {Translational Psychiatry}, volume = {9}, journal = {Translational Psychiatry}, organization = {FTLDc Study Group}, doi = {10.1038/s41398-019-0381-1}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-225308}, year = {2019}, abstract = {C9ORF72 mutations are the most common cause of familial frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS).

Our multicenter, 18F-fluorodeoxyglucose positron-emission tomography study of 22 mutation carriers with FTLD, 22 matched non-carriers with FTLD, and 23 cognitively healthy controls provided valuable insights into functional changes in C9FTLD: compared to non-carriers, mutation carriers showed a significant reduction of glucose metabolism in both thalami, underscoring the key role of the thalamus in C9FTLD. Thalamic metabolism did not correlate with disease severity, duration of disease, or the presence of psychotic symptoms.

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.

Most interesting is the strict resonant excitation of such emitters to control their occupation coherently and to generate close to ideal quantum light, which is of utmost importance for applications in photonic quantum technology. To date, the approaches and experiments in this field have been performed exclusively using bulky lasers, which hinders the application of resonantly driven two-level emitters in compact photonic quantum systems. Here we address this issue and present a concept for a compact resonantly driven single-photon source by performing quantum-optical spectroscopy of a two-level system using a compact high-β microlaser as the excitation source. The two-level system is based on a semiconductor quantum dot (QD), which is excited resonantly by a fiber-coupled electrically driven micropillar laser. We dress the excitonic state of the QD under continuous wave excitation, and trigger the emission of single photons with strong multi-photon suppression (g\(^{(2)}\)(0)=0.02) and high photon indistinguishability (V = 57±9\%) via pulsed resonant excitation at 156 MHz. These results clearly demonstrate the high potential of our resonant excitation scheme, which can pave the way for compact electrically driven quantum light sources with excellent quantum properties to enable the implementation of advanced quantum communication protocols.}, language = {en} } @article{LudwigDelforgeFaconetal.2018, author = {Ludwig, Heinz and Delforge, Michel and Facon, Thierry and Einsele, Hermann and Gay, Francesca and Moreau, Philippe and Avet-Loiseau, Herv{\´e} and Boccadoro, Mario and Hajek, Roman and Mohty, Mohamad and Cavo, Michele and Dimopoulos, Meletios A and San-Miguel, Jes{\´u}s F and Terpos, Evangelos and Zweegman, Sonja and Garderet, Laurent and Mateos, Mar{\´i}a-Victoria and Cook, Gordon and Leleu, Xavier and Goldschmidt, Hartmut and Jackson, Graham and Kaiser, Martin and Weisel, Katja and van de Donk, Niels W.

As more than 30\% of them could not previously be quantified at this taxonomic resolution, relative abundance estimates based on mOTUs are more accurate compared to other methods. As a new feature, we show that mOTUs, which are based on essential housekeeping genes, are demonstrably well-suited for quantification of basal transcriptional activity of community members. Furthermore, single nucleotide variation profiles estimated using mOTUs reflect those from whole genomes, which allows for comparing microbial strain populations (e.g., across different human body sites).}, language = {en} } @phdthesis{Machwart2024, author = {Machwart, Khaled}, title = {Modulatorischer Einfluss von Levosimendan bei dem Isch{\"a}mie-Reperfusionsschaden auf die myokardiale Mitochondrienfunktion}, doi = {10.25972/OPUS-36102}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-361021}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2024}, abstract = {Die vorliegende Studie untersuchte den Effekt von Levosimendan auf die mitochondriale Funktionen im Herzmuskel, insbesondere im Zusammenhang mit dem Isch{\"a}mie/Reperfusions-Schaden.
