    Identification of regulatory variants associated with genetic susceptibility to meningococcal disease

    Non-coding genetic variants play an important role in driving susceptibility to complex diseases but their characterization remains challenging. Here, we employed a novel approach to interrogate the genetic risk of such polymorphisms in a more systematic way by targeting specific regulatory regions relevant for the phenotype studied. We applied this method to meningococcal disease susceptibility, using the DNA binding pattern of RELA - a NF-kB subunit, master regulator of the response to infection - under bacterial stimuli in nasopharyngeal epithelial cells. We designed a custom panel to cover these RELA binding sites and used it for targeted sequencing in cases and controls. Variant calling and association analysis were performed followed by validation of candidate polymorphisms by genotyping in three independent cohorts. We identified two new polymorphisms, rs4823231 and rs11913168, showing signs of association with meningococcal disease susceptibility. In addition, using our genomic data as well as publicly available resources, we found evidences for these SNPs to have potential regulatory effects on ATXN10 and LIF genes respectively. The variants and related candidate genes are relevant for infectious diseases and may have important contribution for meningococcal disease pathology. Finally, we described a novel genetic association approach that could be applied to other phenotypes

    Die immensen Fortschritte der neonatologischen Intensivmedizin in den letzten Jahrzehnten haben ein Überleben von extrem unreifen Frühgeborenen ermöglicht. Dieser Erfolg ist mitunter mit einer beträchtlichen Langzeitmorbidität für ehemalige Frühgeborene verbunden, was potenziell schweres Leid für das Kind und seine Familie mit sich bringen kann. Der vorliegende Beitrag stellt eine Aktualisierung der 2005 publizierten nationalen Leitlinie für Österreich zur Vorgangsweise bei extrem unreifen Frühgeborenen an der Grenze der Lebensfähigkeit dar. Er soll einen Leitfaden bieten, anhand dessen im individuellen Fall eine verantwortungsbewusste Entscheidungsfindung ermöglicht wird. Es werden rechtliche, ethische und medizinische Aspekte diskutiert sowie eine individuelle Empfehlung für das postnatale Management von extrem unreifen Frühgeborenen der Schwangerschaftswochen 22+0 24+6 ausgesprochen.The enormous progress in neonatal intensive care during the last decades has enabled the survival of extremely premature infants. This success is at times associated with considerable long-term morbidity of these patients, potentially causing significant suffering and distress for the child and the family. The current manuscript presents an update of the Austrian national guidelines for the management of extremely premature infants at the limits of viability published in 2005. Rather than being strict guidelines, this manuscript is intended to provide caregivers with consensus practice recommendations to facilitate responsible decision-making in individual cases at the border of viability. Ethical, medical and legal aspects are discussed and an individual recommendation for the postnatal management of extremely premature infants born at 22+0 24+6 weeks gestational age is given.(VLID)365518
