Arbeitsgruppe Prof. Dr. Hildegard Kehrer-Sawatzki
Zusammensetzung der Arbeitsgruppe:
Prof. Dr. Hildegard Kehrer-Sawatzki |
Forschungsschwerpunkt der Arbeitsgruppe ist die Charakterisierung der Mechanismen von genomischen Erkrankungen, insbesondere von Mikrodeletionen in der NF1-Gen Region, die 1 bis 2 Megabasen an DNA umfassen und bei etwa 5% aller Patienten mit Neurofibromatose Typ 1 (NF1) festzustellen sind. NF1 Mikrodeletionen gehören zu den sogenannten genomischen Erkrankungen, deren Entstehung durch die genomische Architektur, insbesondere durch segmentale Duplikationen bzw. Low-Copy-Repeats gefördert wird. Vor allem die nicht-allelische homologe Rekombination (NAHR) zwischen segmentalen Genomduplikationen spielt eine wichtige Rolle bei der Entstehung von genomischen Erkrankungen und damit den NF1 Mikrodeletionen. Fragestellungen, die in der Arbeitsgruppe bearbeitet werden sind:
