Vererbte Magersucht

Bei der vererbte Magersucht liegt eine erblich bedingter besonders schlanker Körperbau vor. Es handelt sich vor allem um eine Ausschlussdiagnose, wobei differentialdiagnostisch Essstörungen und generalisierte Lipodystrophien abzugrenzen sind. Die Störung wird durch Mutationen im AGRP-Gen verursacht.
